What is mobile app development, how does it work, and why is it important to your business? Here’s everything you need to know about mobile app development for small business.

  • Mobile app development is the creation of software intended to run on mobile devices and optimized to take advantage of those products’ unique features and hardware.
  • The types of mobile apps that developers create include native apps, hybrid apps and HTML5 apps.
  • The mobile app development business is set to grow to nearly $600 billion in 2020. 

Due to the exploding popularity of smartphones and tablets, mobile application development is an increasingly popular medium of software creation. In fact, mobile apps have become an essential element of most businesses, and revenues are projected to hit nearly $600 billion in 2020. This prolific and growing industry has attracted businesses from every corner of the marketplace as consumers detach themselves from desktop computing and turn to their mobile devices. 

The creation of mobile applications has much of its roots in traditional software development. The end result, however, is software intended to utilize the unique features and hardware of mobile devices. Modern smartphones are equipped with Bluetooth, NFC, gyroscopic sensors, GPS and cameras. They can be used for virtual or augmented reality, barcode scanning, and more. Mobile apps should utilize the full range of smartphone features, which is easier said than done. 

With desktop PC software development, programmers must create an application that can operate on a minimum set of hardware. The same goes for mobile applications, though the hardware variances in this instance are much more minimal. At the same time, the hardware in smartphones and tablets doesn’t quite match that in laptops and desktop computers, which means mobile apps must be designed to show optimal performance 

For example, a gaming app would be limited in its graphical elements because of the less powerful graphics processors in mobile devices. With that said, cloud computing is making it easier than ever to accomplish mobile gaming. Popular games such as Fortnite, Hearthstone and PUBG connect players across computers, phones and even consoles.

Mobile app development considerations

Solving the issue of performance on any given device ultimately depends on developing an app natively on that device. This means designing the code specifically for the hardware on a particular device. In the instance of iOS devices, this proves quite easy, as mobile developers only need versions of the app for the iPhone and iPad to achieve universal usability. For Android devices, however, each smartphone or tablet runs on different hardware and varying versions of the operating system.

Web-based apps, on the other hand, don’t depend on the device; they run off of a web browser, making them cheaper to develop and easier to access. However, their performance doesn’t compare to that of a native app. For example, with web apps, you cannot use the phone’s full features or send proper notifications, and they look less professional.

Types of mobile apps and programming languages

Like desktop software, mobile apps are designed using a wide range of programming languages and frameworks. While the most popular operating systems, iOS and Android, have done an excellent job of standardizing the types of mobile app development available to programmers, apps can still vary. Here are some mobile app types:

Native apps

These are apps created for a specific platform (iOS or Android) using the software development tools and languages supported by those operating systems. iOS uses Xcode and Objective-C, whereas Android uses Eclipse and Java. Developers often prefer native apps because of their ability to utilize a device’s full potential. With smart home devices becoming more common, developers are creating unique applications that integrate things like wearables, Internet of Things sensors and smart screens for personalized experiences. Of course, development for each platform is a costly and time-consuming process that doesn’t work for all businesses.

HTML5 apps

Based on the near-universal standards of web technologies – HTML5, JavaScript and CSS – this type of mobile app takes a write-once-run-anywhere approach to mobile development. Apps developed in this framework are compatible with many platforms and require only minimal changes to ensure complete functionality on each operating system. HTML5 apps can still send desktop notifications and trigger interactions through email and other avenues. Don’t discount web apps’ usability, but keep in mind that consumers are more likely to use a native app. A study from Oracle found that millennials spend 90% of their mobile time in apps and 10% in web browsers.

Hybrid apps

These apps entail the creation of a container developed in the native system that makes it possible to embed an HTML5 app within it. This allows apps to make use of the diverse and unique elements of each native system. Before creating your own branded app, consider utilizing existing apps for greater impact. For example, by using mobile-focused marketing on services such as Yelp, Facebook and Google Maps, you can drive traffic to both your website and brick-and-mortar location.

Software development kits

Mobile app development requires access to software development kits (SDKs) that provide a simulated mobile environment for programmers to design and test code. However, creating an app does not require full use of these kits. For example, developers can create mobile games using Unity and then use the Android SDK to ensure its deliverability on mobile devices. Developing apps for iOS requires a paid iOS developer license, whereas the Android SDK is freely available to users. 

iOS and Android have similar mobile market shares (47% and 52% respectively), but developing for Apple is somewhat easier in that you don’t need to worry about a wide range of devices from different manufacturers. Whichever operating system you choose, however, there are barriers to entry.

Mobile app development requirements

Mobile app development is changing constantly. Typically, every six months or so, a new version of an operating system rolls out with unique features that mobile apps can utilize. Developing for a specific version of the operating system, or even for a native operating system, usually requires developers to try multiple solutions to find the one that suits their development needs.

Failure to keep up with development updates could cause catastrophic cybersecurity issues. Consider the costs of developing an app, which can range from $5,000 to $15,000 to start, plus the costs for continued development and maintenance. If Android or iOS releases a new OS update, you can be delisted quickly for being incompatible. 

Developing an app is only worthwhile if it’s a great app. A poor user experience will drive customers away. Be mindful of the user experience and realistic about your budget.

App development process

Regardless of the type of project you want to bring to life, the app development process has six key steps. Breaking the project down into these simple steps will help you develop your app quickly and efficiently. 

  1. Idea: When brainstorming app ideas, put some research into answering a few questions about it. What problem does this app solve? Who is the target audience? Why are these features important? Do your competitors have similar apps.
  2. Design: Next you’ll design a user interface (UI) and user experience (UX) to navigate the user through the app and make it easy to follow.
  3. Development: During this stage you’ll write the code for your app, develop the code and start preliminary testing.
  4. Testing: By testing your app, you’ll determine its quality, any malfunctions and what you can improve.
  5. Launch: Once your app is bug-free and ready to go, you can publish it on marketplaces like the Apple App Store and Google Play.
  6. Marketing: Create a marketing strategy to get users to download your app and give you feedback on how to improve user engagement.

Best platforms for building a mobile app

Just a few short years ago, if you wanted to develop an app, you had to either know how to code or pay someone to develop the app for you. Fortunately, low-code and no-code apps and services have appeared over the past several years to help you bring your vision to fruition. Here are five platforms to help you build a mobile app: 

  1. Appery.io: Appery is a mobile app builder that entirely runs in the cloud, meaning there is no software to install or download. The platform offers a visual editor where you can drag and drop new components into your app and auto-generates code for these components.
  2. Mobile Roadie: For brands looking to build a very visual app, Mobile Roadie is a platform that works with various media, including RSS feeds, Twitter and Google News. The builder allows you to send out push notifications and pulls data from a variety of sources, such as XML, JSON, PHP, CSV and HTML.
  3. GoodBarber: If you want to control every aspect of your app but don’t have much code-writing experience, GoodBarber is a great platform for you. You can build an app for either an iPhone or Android device and even use the app to replace your current website, as the apps can be optimized for desktop and tablets.
  4. Appy Pie: As a cloud-based DIY app builder, Appy Pie allows you to create and publish an app for any platform without any programming skills. Since the platform is based in the cloud, you can drag and drop all the elements online. Once your HTML5 app is complete, you can send it to be used on iOS, Android, Windows and even Progressive platforms.
  5. AppMachine: Another easy-to-use platform with a drag-and-drop interface, AppMachine allows you to easily build an app while adding your own unique style to it. You can choose your own fonts, pictures, colors, and paths and be in complete control of your layout. It also offers in-service app testing abilities, so you can see how it’ll work on computers and mobile devices and note what changes need to be made.

The mobile app development industry is going through a transformative phase. With the advancement in micro-processing technologies, you will be able to run mobile applications on multiple platforms. For example, apps built for mobiles will run seamlessly on desktops in the coming years. Moreover, mobile apps built with Flutter or React Native will work on Android Phones, iPhones, Macs, as well as PCs. But before we get more in-depth, let’s dig into the mobile app usage statistics to understand how users are spending their time using mobile phones, and what are the opportunities in building your own mobile application.

Mobile App Development Lifecycle 2021

There are over 3.5 billion smartphone users worldwide, so there is no doubt that the industry is healthy and thriving. Stats are growing steadily, without any indications of slowing down. And studies show that an average American checks their phone at least once every twelve minutes, and over 10% of these people check their phone about every four minutes. There are some more statistics to keep in mind.

  1. People spend over half of the time they spend with digital media on mobile.
  2. Smartphone users spend 90% of their screen-on time using mobile apps.
  3. Over 85% of consumers prefer native apps over mobile cross websites.
  4. Revenue from mobile apps is set to cross $693 billion in 2021.
  5. The average consumer has over 30 apps installed on their device.
  6. An average user spends about 35 hours per month using mobile apps.

The statistics are motivating for anyone who wishes to build or develop a mobile app. But before we jump to any conclusions, let’s understand the exact process for mobile app development. Although it sounds very lucrative to build a mobile app to get a piece of the billion-dollar pie, the decision needs thought strategy and planning. The fact also states that your app will be competing with over 1.5 million applications on the Google Play Store and Apple’s App Store.

What is Mobile App Development?

Mobile app development is a process for building mobile applications that run on mobile devices. These applications can either be pre-installed or downloaded and installed by the user later. They use the network capabilities of the device to work computing resources remotely.  Hence, the mobile app development process requires creating software that can be installed on the device, and enabling backend services for data access through APIs, and testing the application on target devices.

To develop scalable mobile apps, you also need to consider screen sizes, hardware requirements, and many other aspects of the app development process. With an increasing number of jobs in the mobile app development industry, it is essential that the process is well defined and understood by entrepreneurs, startups, and especially developers.

Mobile App Development Platforms

The two most important mobile app platforms are iOS from Apple Inc. and Android from Google. iOS is Apple’s proprietary mobile operating system built specifically for iPhones. Android, however, runs on mobile devices manufactured by various OEMs, including Google.

While there are many similarities between the two, however different software development kits (SDKs) are used for different platforms. Apple uses iOS exclusively for their own devices, while Google has made Android available for other companies that meet specific requirements. Developers have built over 1.5 million applications for both platforms to date.

Alternatives for Developing Mobile Apps

You can approach mobile app development in four different ways:

  1. Build Native Mobile Applications
  2. Build Cross-Platform Native Mobile Applications
  3. Build Hybrid Mobile Applications
  4. Build Progressive Web Applications

There are advantages and disadvantages to building an application, no matter which approach you choose. By choosing an approach that matches your strategy, you can achieve the desired user experience, avail computing resources, and build native features required for your application.

Why Choose Native App Development?

Choosing native app development helps when you want to use native capabilities offered by the platform. Native apps can access the hardware capabilities of the devices like GPS, camera, microphone, which helps in quicker execution of features making it easier to build a rich user experience.

Push notifications are much easier to implement on native development. For example, push notifications to go through iOS Server (APNS) and Google’s Cloud Messaging Platform. Native apps have fewer bugs, as the code is compiled in the native language.

Why Choose Cross-Platform App Development?

The market is divided about 50-50 between iOS and Android. Your potential customer could be on any of the platforms, and sometimes on both. Building separate apps for both platforms requires an adequate budget, and not all companies have that. Moreover, developing native platforms can make it harder to offer the same amount of speed and functionality required by your app.

Choose cross-platform development if you wish to align the user experience across all the platforms; you wish to have one development team publishing for both the platforms; and you don’t have the budget and time to build and maintain two different apps separately.

Why Choose Progressive Web App Development?

Progressive Web Applications (PWAs) are written in traditional web languages like Javascript, HTML5, CSS, and such. These apps are only accessible through the browser of your device. So, choose to develop a PWA if your user will have uninterrupted access to network connectivity, and they can solve their issues through the browser itself, without requiring any native capabilities of the device like camera, machine learning module, GPS, gyroscope, and such.

With that in mind, let’s understand the mobile app development process step by step and get to know everything you need to follow a systematic mobile app development process to build your next great app.

Mobile App Development Process

To build an application, you need a step-by-step process that can help you build mobile apps quickly. There are three important steps:

  1. Understand the requirement
  2. Develop the Product
  3. Test the product.

Build an App Development Strategy

The first step in the mobile app development process is to create a strategy by defining why? What is the objective of your app? How will your mobile app solve an industry problem? What is your business model? How much are you ready to invest in building this app? What is your revenue model? How will you market your app, and to who? Answering these questions will give you a fair idea of how you can move forward with your mobile app development process.

You can start by defining the user persona. For example, suppose you are planning to build an eCommerce app. In that case, you will define your user persona by understanding your user’s age, their mobile usage habits, their preference, and specifically answering why and how they will find your mobile app users. Based on this, you can create an MVP (Minimum Viable Product).

To build an effective strategy, you will have to do some of the following things:

Brainstorm your app idea

Building a mobile app starts with an app idea. However, you require an extensive amount of brainstorming to develop an ultimate list of features you can offer your customers. You can start with the essential elements and note down other lesser crucial features as they are revealed to you. Who knows, you might surprise yourself with ideas you never knew you could implement. Sit together with your team, and ask them for all the ideas they can come up with.

Market Research, Mobile App Development Tech Stack

Before you start, here are some questions you can ask yourself:

  1. Who is your target audience?
  2. How will your customers use the application?
  3. Are there any better alternatives already available?
  4. What will your application do that other application won’t?
  5. What business model are your customers following?
  6. What language, frameworks, and technologies will you use?
  7. How many uses are paying for your type of mobile application?
  8. What is your budget?
  9. How long will it take to build your application?

Define your Minimum Viable Product

Once you are clear about all the functionalities you can include, the functionalities your users will like to use from the start, you define what your minimum viable product would look like. A minimum viable product is the version of your app that has enough features to put it in front of your early customers so that you can receive feedback on product features and further development.

You build a minimum viable product for the following reasons:

  1. Test the product market using minimum resources
  2. Get investors to see the vision behind your app
  3. Quickly learn what works and what doesn’t
  4. Waste minimum engineering hours
  5. Get the product in front of early customers fast
  6. Use it as a base to build other products
  7. Test developer’s ability to build and scale product

Key elements of a minimum viable product (MVP)

  1. Functionality – offer clear value to the users
  2. Design-build minimal but highest quality standard design
  3. Reliability – make the production quality top notch
  4. Usability – make the user experience intuitive and refined

With a clear strategy in mind, you will be able to focus on your app development idea. Building a mobile app development strategy will help you analyze and plan your progress.

Analyse and Plan your App Development

The strategy is the starting point of all project development. Now, once you have a strategy in hand, start turning those visions into achievable goals. Start the analysis and planning by clearly defining how you can use the functionalities to build use cases and meanwhile, create a list of functional requirements.

This will help you build a product roadmap. You will be able to convert that strategy into a step by step process that you can turn into priorities, and then group them into delivery milestones. You must also have your minimum viable product defined, which will help you cut down on costs, and prepare for the initial launch.

Different operating systems require different technology stacks. Choose your tech stack based on your requirements. Whether you are building a native mobile application, a cross-platform mobile app, or a hybrid application, you will need to make a list of technologies required, and start hiring developers with expertise in your chosen mode of mobile app development.

Plus, you will need to finalize a name for your mobile application. To find the perfect name, you might want to contemplate your application’s features, differentiate the name using wordplay, keep it short and easily memorably, searchable, and probably an action word. Many app developers also go with obvious names, and sometimes they differ by trying to connect with consumers’ opinions. You should also keep in mind the process of App Store Optimization, which is important if you want to be found by users searching for apps similar to yours.

Build UX/UI Design

How your mobile application looks and feels makes a great deal of impression on the minds of your users. Whether it be a full-fledged application of an MVP, you have to make sure that the design is top-notch and that it offers the highest level of user experience. Designing mobile apps requires the understanding of the two important concepts of design:  User experience and user interface.

What is User Experience Design?

User experience is what customers feel when they use your products. In our case, the design should be such that it creates a specific emotional response from the customer after using the app. User experiences include factors like design, accessibility, marketing, usability, system performance, ergonomics, HCI, and also utility. With an increasing number of companies focusing on user-centered design, creating an intuitive user experience for your mobile application is a no-brainer.

What is User Interface Design?

Designers make sure that the mobile application looks crips and pleasurable. User Interface Design is the process of making your app look perfect, following the latest design trends, so that it complements the user experience. Designers often use principles like the structure principle, the simplicity principle, the visibility principle, the feedback principle, the tolerance principle, the reuse principle, and more.

Mobile App Design Process

Designing is much more than learning how to use design software. You can learn to design your mobile application yourself or ask someone to help you. But above everything else, the design is about understanding the product inside out, and its capabilities, features, and functionalities. The design should always keep the end-user in mind. The design process we follow at OpenXcell is as follows.

  1. Building User Flow / Diagram for each screen
  2. Creating Wireframes
  3. Choosing Design patterns, palettes, and elements
  4. Creating mockups
  5. Creating an animated prototype and asking testable questions
  6. Give final touches to the mockup based on user feedback

Wireframes

Most designers start by making rough sketches on paper. To simplify, wireframes are digital sketches, done using a wireframing tool, which you can also do using pen and paper. Wireframes are concepts, not finished designs. They simply help you understand the visual structure of your app’s features using low-fidelity mockups.

Wireframes

When you are designing wireframes, the focus has to be made on aesthetics and how the user will experience it. Color palettes and design elements are not required now. Wireframes are used to quickly understand what you want to be designed. It is important that you design that is specific to the product. No matter which device you are on, it should be intuitive and user-friendly.

Style Guides

A style guide is a set of rules for the design. User interfaces can get tricky. Wireframes can be misunderstood. But if you have a style guide, your mobile app UI designer will understand what fonts have to be used, what color palette has been chosen, which icons are to be placed where, and many other important questions they might ask before designing.

Style guides create a base for the process of long-term evolution, switching design and development between parties, developing for differences in the platform. It also helps in sharing topics. Some of the elements you can consider for mobile app style guides are as follows:

  1. Fonts
  2. Colors
  3. Layouts
  4. Graphics
  5. Components
  6. Menus and Bars
  7. Dialogs and Alerts

Further reading → App Design style guides Example

Mockups

Eventually, you will move past the prototype phase, and build the final version of your mobile app development. These designs are called mockups, or high-fidelity designs. Mockups combine the wireframe and the style guide to build the final version, which can be sent for prototyping. You will expect further modifications in the structure, workflow, and even aesthetics at this stage to make it look and feel exactly like you want it to.

Some of the popular tools for building mockups are FigmaSketchPhotoshop, and Adobe XD.

Prototype

Wireframes are good. But you will need interactivity to test the features so that you can receive feedback. Prototyping is about turning low-fidelity wireframes into ready designs that can be shared with your teams, friends, and everyone who can use it to offer their quality suggestions and feedback.

Most teams use products like InvisionApp to prototype their app. However, some companies also use Xcode to prototype their apps directly into the development environment.

Prototyping is essential if you are looking to pitch your app to investors. You can include all the functionalities without going through development. For testers, it helps by offering a real feel for what it would be like to use the application.

Begin App Development

There are three important aspects of app development:

  1. Technical architecture
  2. Technology stack
  3. Development milestones

Most of mobile app development projects have three integral parts:

  1. Mobile Backend server technologies
  2. Application Programming Interface (APIs)
  3. Frontend development

What is Mobile App Backend Development?

What is Mobile App Backend Development

What your users will see is the front end. The development that is required from the side of the server is the backend. Mobile app backends are used to store, secure, and process data. It refers to the activities that will happen behind the scenes when a user is interacting with your mobile application. Developing a backend for your mobile is used for sending information for processing on the server. Signups, logins, messaging, storing data on the cloud, answering user queries, and such other things happen in the backend.

Backend development focuses on storing information in a remote database, scripting to add logic to the interactivity, and creating architecture that makes it quick and easy to sort through the information.

Applications like a calculator, camera, notes, compass, voice recorder, and such don’t require a backend development. They run on the mobile app without any network connectivity, or the requirement to store or retrieve data from a remote server. However, apps like Amazon, Netflix, and Uber can’t run without a connected backend.

Application Programming Interface (APIs) Development

Mobile apps have evolved into a state where they are constantly communicating with servers. Very few applications operate without connectivity, which means they use the backend, web service, or APIs. These APIs could be provided by companies like Amazon, Google, Facebook, or others, or developed internally by the mobile app development teams.

Most of the mobile API Development is done using RestAPI, which is also one of the simplest choices for anyone building mobile apps. It helps users quickly interact and connect with a remote cloud data server. However, making requests through the network can create major problems if not done right. Some things to take care of when building mobile APIs are:

Understand how HTTP protocols work
  1. Understand how web services work. There is a wide variety of APIs available, however, most of them are based on REST, which returns data in JSON format.
  2. Understand how HTTP protocols work. REST relies on HTTP protocols to handle data, so it is important to get familiar with the workings of HTTP URLs, the process of data transfer, and how it handles remote actions.
  3. It is also important to learn how REST maps URLs to make the required requests.

Should you buy or build APIs?

There are two ways to integrate APIs to your mobile application. You can either build it yourself or you can buy from an existing API provider.

Purchasing a ready API and integrating it is the easiest because it saves time and money in the sense that you don’t need a developer to understand and implement API integration for you. However, building your own API gives you much more freedom and allows you to include or exclude features as per your requirement.

Before assembling a team and building your own custom API, it is better to explore the available options. Instead of reinventing the wheel, simply use what is already available even if that comes at a cost of saving your time to help you reach the market faster.

Using Common Architecture

When and if you decide to build your own API, it is best to go with a common architecture. It offers a general baseline for development which most developers are used to developing. This speeds up your mobile API development process. There are four different types of common architecture, which include pragmatic REST, web services, event-driven, and hypermedia. For mobile app development, the most preferred common architectures are pragmatic REST and event-driven.

Documenting the Mobile API Development Process

Developing an API is easy. However, teams evolve, and there is always going to be someone new looking at your code. Having a clear API process documentation can help you see the history, as well as the current state of API. This makes future updates easier. Another benefit of documenting your API development process is that it allows others to use your API. If you want other developers to use your API, you will need solid documentation to help you with the code.

Focusing on Security

Whether you use a readymade API or build your own, it is important that you keep the security measures in check. It is always an important component for developers. Moreover, it is crucial for mobile development. Developers have to access control mechanisms, privacy control, and secret keys before invoking web-based APIs. There was a time when APIs had their own security. However, today, there are API standards like OAuth2, TLS, and Open ID to make the API integration simpler.
