Mobile operating systems like Android, iOS, Windows Phone, etc., are the base of this kind of app development. In particular, industry-specific enterprises like legal, retail, financial services, food, travel, automobile, etc., need to develop it.
If something happens somewhere in a blockchain, it is shared with every member of the entire network. And everyone can store that information on their devices. That’s why Blockchain now has vast potential for many industries, and blockchain mobile app development has become so urgent now. Moreover, blockchain technology enhances data privacy and security, making it inevitable for mobile app development.
IoT-The Internet of Things is the future technology that is already becoming a reality. Once upon a time, it was a science fiction that people use in various fields of daily life, including health, agriculture, and manufacturing. Mobile applications work as a connection between those devices.
Therefore, it is not possible to control IoT devices without mobile application development. Moreover, the developers are creating many great apps day by day to implement each such device beautifully.
Fintech is the term made from finance and technology. Such mobile applications are developed to perform various financial services automatically. Financial sectors such as Blockchain, banking, budgeting, and many more need fintech mobile app development a lot in this automation era. Nowadays, more platforms like education, retail banking, stock market, investment management, etc., are using fintech software in their day-to-day working process. That’s why this kind of technology is gaining more popularity than ever.
With augmented reality (AR) technology, users can interact with virtual reality using real-world objects. To do that, people need an app to manage and control AR devices. Augmented reality is a little different from virtual reality. The user must use a headset to use it.
In addition, augmented reality app development will have a much more significant impact on technology soon, which has already begun.
Enterprise mobile applications are developed for different organizations to perform their tasks. This type of app belongs to the organization and is used only by its own workers. In addition, various organizations develop mobile enterprise apps to provide different services to their target customers.
Custom Mobile App Development
Custom mobile applications are essential for any business. Banks, developer companies, educational institutes, and many other business organizations develop custom mobile apps for their own work. And the craving for such apps is increasing day by day.
Mobile Banking App Development
Digital banking services are becoming more accessible through mobile banking app development. With mobile bank applications, users can quickly check their balance, perform fund transactions, and many more. Mobile banking applications also allow users to pay any bills from home or anywhere. So, there is no question about the importance of mobile banking app development.
Businesses, Banks, and Financial Institutions are the core platforms that develop financial mobile app development. For example, for providing online banking services, every bank is now leveraging financial mobile app development.
Financial works like Stock trading online allow users to carry out trading electronically. Besides, this kind of app provides a fast funding solution like micro credits [Inventor of Micro Credits: Dr. Muahammad Yunus] or microloans.
We all are interacting with consumer and enterprise apps every day. Mobile applications such as Google Chrome, Facebook, Uber, Netflix are great examples of consumer mobile app development. These applications are helping people to use the web in a new way.
Wearable technology is what the user can wear on the body. Such software is being used many times nowadays with any wearable device, not just clothes. Today’s most popular wearable devices are Smart Watch, Fitness Tracker, Smart Glass, and More. And for such devices, wearable app development is required. In this step-by-step guide, I will discuss starting an app from scratch. But before going any further, let’s know what app development is first.
Mobile App Development Lifecycle
Smartphone App Development Lifecycle follows the application development principles stage by stage. Thus, every step from research to deployment or maintenance completes a mobile software development lifecycle together.
Usually, the development of mobile applications starts with discovering the pros and cons of the service idea. Then, it continues with market research, target group study, and project estimation.
It is crucial to connect the customer base to your business or service area. For example, suppose you are running a retail business to take advantage of mobile apps to interact fast with your customer base.
Besides, a mobile app can be a medium for your customers to connect with your brand conveniently. It will also enable more accessible purchases and build a strong relationship between you and your customers.
Whatever your goal with the mobile app, you must ensure its good functionality. And, of course, make sure your application is industry standard to provide a better user experience for your customers.
Before making a mobile app, you might want to learn more about the mobile app development lifecycle.
There are some significant steps involved in smartphone app development. So, try to make a good understanding of each step at the beginning of the process.
Have a look at the significant steps of mobile application development first. Then, we will discuss the process step by step.
- Planning Stage
- Application Wireframe Design
- Quality Assurance
Mobile Application Development Platforms
iOS from Apple Inc and Google’s Android are the two most important mobile app platforms. iOS is Apple’s owned smartphone operating system only for iPhones.
On the other hand, Android is an open-source operating system for mobile devices. It is also a related open source project led by Google. Google and other OEMs manufacture this platform to run intelligent devices.
Of course, there are a lot of similarities between these two platforms. But manufacturers use different app development kits (SDKs).
Apple Inc uses the iOS app development platform exclusively for their proprietary devices. Yet, Google has made Android accessible for Android App Development. But to use Android, they must meet specific requirements.
However, developers have made over 2m (two million) mobile apps for both platforms to date. Here, you can see the Reference: Number of Apps Developed for more information.
Alternative Ways to Develop Mobile Apps
There are four different ways to go for mobile software development. Of course, you will face both advantages and disadvantages whatever method you choose to develop a mobile app. But consider a method that meets your strategy and gives your desired user experience.
Look also for the availability of computer resources and native features for your mobile application development. Now let’s check which way is going to align the best with your needs.
Native Mobile App Development
App platform owners like Apple and Google use tools and SDKs (software development kit) to build native mobile apps. The purpose of this development is to run the apps natively.
A native mobile application needs a specific programming language such as Objective C for iOS or Java for Android OS. That is why native mobile apps give better performance, and they are highly reliable.
But, this kind of native mobile app development is costly. For example, various video games for mobile devices are in this category. So, let’s see some of the benefits of native mobile app development here.
Benefits of Native Mobile App Development
- Provide best runtime performance
- More Secure Applications
- More Interactive And Intuitive
- Native apps have accessibility to all the features of devices
- Developers faceless bugs while building native apps
Cross-Platform Mobile App Development
Cross-platform app development allows developers to create apps compatible with many OS like Android, iOS, Windows, etc.
In this process, app developers can use various programming languages. Later, they compile the code for a different platform.
As a multi-platform mobile app development, it is evolving very fast. Cutting-edge technologies are also making it more dynamic and attractive nowadays. Despite some cons, cross-platform has some great benefits too. The advantages of this kind of mobile software development are below.
- It offers a unified user experience.
- Sharable code for many platforms
- Provide faster app development
- Promising for a broader audience
- And provide native style
Hybrid Mobile App Development
Some say that Hybrid App Development and cross-platform are the same. But there are some differences between Hybrid and Cross-Platform Apps. However, Hybrid apps are popular as they need web containers with browser runtime.
Though Hybrid applications provide low support for native devices, they have a lot of benefits.
- Functional without connecting to the device
- Integration ability with the mobile’s file system.
- Web-based services
- Embedded application for dynamic contents
- Web development tools are suitable to build
Progressive Mobile Web App Development
Progressive apps are web applications that also run on mobile devices. Therefore, they don’t need native or cross-platform development.
You will need to install any app from the app store. But progressive apps skip the app store installment and use traditional channels. So let’s learn what the key features progressive mobile app development has are.
- Progressive apps run on both web and mobile platform
- Users don’t need to install the app
- They can run the app in the browser online using a URL
- App performance depends on the browser’s capability
Besides these four, mobile cloud apps are also popular for their fast responsiveness. Moreover, mobile Apps Driven by Cloud don’t need to be preserved on the device permanently.
Step-by-Step Process of Mobile App Development
Countless mobile apps are being published on Google Play and Apple App Store every day. These apps include games, social networks, eCommerce, and many more.
On the other hand, you will need an extended timeframe and a lot of expertise to build an application. So, it is not an easy process at all.
Generally, a developer needs to follow many things in the whole mobile app development process. To help you learn the basic ideas, I will discuss every aspect from planning to development.
Let’s begin with the most crucial steps of mobile app development. The steps include planning, strategy, designing, development, deployment, and so on.
Brainstorming for App Idea
App development is all about turning your imagination into reality. It means your idea is going to have a form through the app development process.
Usually, the main goal of developing an app is to solve a specific problem you’re facing. So, think about which problem you want to fix through mobile app development. Then brainstorm for the potential solutions the app will provide. Ask yourself the relevant questions about the problem. And find out the best ones to include in the application.
You can talk to other people about why no one ever created an app for the problem. You should go deeper to understand and to find great ideas for the solutions. After having a total grasp of the problem and its solutions, focus on developing a mobile app.
Choosing App Development Strategy
You will need to find some answers to some questions before choosing an app development strategy. Sorting out the below facts will help you develop an efficient strategy-
- First, define why you need to develop the app
- Define the objective of your app
- What will be the use of your app in solving an industry problem
- Define your business model
- Your investment in building the app
- Your revenue model and the audience of your application
Sorting out these facts, you will have a clear idea of the mobile app development process. After having the data from this, you can list MVPs (Minimum Viable Product). But I will discuss MVP later in this article. So, keep reading.
Choosing Technology Stack for Mobile App Development
Making a new app is like making a new house. In that case, you need practical tools and materials to make your house strong. Mobile app development is not different from that.
So, you should choose the best mobile app technology stack. A combined technology stack with the programming language, platform, framework, and other SDKs tools.
Here are some categories of the mobile stack you will need to consider.
- Mobile stack for Front-end development
- Mobile stack for Back-end development
- Development stack
- And Supporting tools
iOS Mobile App Development Stack
Different platforms need different technology stacks to develop mobile applications. For example, iOS and Android are different structures, and they both need different styles & technology.
Apple Inc. uses two major programming languages to develop its iOS mobile application. These are-
- And Swift
Objective-C is a programming language that is only used to develop iOS applications. Though it has object-oriented potential and dynamic runtime, many prefer Swift to avoid complexity.
On the other hand, Swift is a new programming language with a lot of benefits. It requires a smaller amount of code and easier to understand and debug. Because of the speed, readability, and simplicity, Swift is preferable to developers in 2021.
According to a survey, 68% (sixty-eight percent) of developers prefer Swift to Objective-C language. Besides programming languages, Apple developers use popular toolsets like AppCode and Xcode. These two are popular iOS app development tools.
In the case of developing UI Frameworks, iOS app developers use UIKit and SwiftUI. These two are almost similar and being used to develop the graphical components. But, SwiftUI supports only the newer versions of iOS. Reference: App Development Stack Survey
Android Mobile App Development Stack
Java is the most popular programming language to develop Android mobile applications. It is also the best for Android APIs and provides a wide variety.
On the other hand, Kotlin is less popular than Java but crucial for mobile applications. This programming language was specially designed for the scientific community. But it is compatible with Java Virtual Machine.
Android Development Tools, Android Studio, and ADT (Android Developers Tool) are great tools for developing mobile applications.
Android Studio is Google’s official platform and used for editing and debugging the code. Apart from that, ADT offers coding and test automation support.
For UI Frameworks, Android provides pre-built UI software. As a result, it is a more accessible platform to build user interfaces.
Besides, Jetpack is another best UI kit to develop Android user interfaces. It also requires less code.
Including MVP (Minimum Viable Product) Elements
The must-have features in an application are called MVP or Minimum viable products. The MVP elements enable faster marketing time, attract early users and make the application fit in the market.
After developing app ideas and strategies, it is essential to define MVPs for your application. Thus, you can include enough features for your early customers. And they can also give feedback while receiving further development.
Here’s why you should develop MVPs for your application:
- You can test the app using minimum resources
- You can identify the faults easily
- You can present the applications for the early customers
- This will work as a base for developing other products
The base of your mobile application will be more substantial if you include some key elements in the MVPs. These elements are minimal but will provide you the highest quality design. Thus, you can get top-notch quality by offering clear value to the users. The key elements are:
- Functionality to offer clear value
- Minimal but highest quality design
- Usability to make it user-friendly
Developing UX/UI Design
The target of mobile app development is to seamless user experiences for your audiences. With this in mind, you should focus on how easily your users can access and adopt the application.
Mobile application development needs two significant design concepts: one is user experience (UX), and the other one is the user interface (UI).
And UI/UX design is the most crucial in mobile software development. So, make your UX/UI interactive, intuitive, and user-friendly.
Most of the developers use pencil sketches to draw wireframes on paper. Unfortunately, it is a time-consuming and very complex process. But using a digital wireframe tool for sketching can be a great alternative to that.
The digital wireframe tool also allows drawing on paper too. So you can do it in both ways. Wireframes are just sketches of your planning.
In this process, the low-fidelity mockups help you to understand the visual concept of the application.
You don’t need to think about the color schemes and styles while building wireframes. Here, the most important thing is focusing on aesthetics and user experience.
A style guide is a set of propositions for writing, formatting, and designing documents. Many often call it a style sheet, but it has different meanings for different purposes.
Style guides help a lot to develop mobile app design strategies. Therefore, making an early style guide will improve your development and the productivity of the developers.
To make a consistent-looking app, you should use app-style guides from Apple Inc. for iOS apps and Google for Android apps.
User interfaces and Wireframes can get tricky or in the wrong way. But a style guide will provide exact direction to your UI designers. It will help them understand what fonts, colors, and icons they should use in specific positions.
Here are some essential things you must consider for your mobile app development style guides.
- Fonts & Colors
- App Layouts
- Graphical Design Elements
- Menus and Bars and their positions
- Dialogs and Alerts Instructions
The final renderings of your visual application are Mockups. These are also called high-fidelity designs of the app. When you apply a style guide into wireframes, it is time you create Mockups.
In that case, Adobe Photoshop can help you create high-fidelity mockups. Therefore, Adobe Photoshop is considered the best tool to design mockups.
Combining mockups, wireframes, and style guides, you build the final version of the app. Then the app will be ready for prototyping.
Prototyping is sharing the app designs with your teams, friends, and others to get their suggestions and feedback. For prototyping the application, most developers use tools like InvisionApp. However, some use Xcode to prototype their mobile app into the development stage.
If you will pitch your app to investors, then the prototyping process is essential for you. In this process, you can add all the features and functionality without going through development. In addition, it helps the testers to get an original feeling for using the application.
Mobile App Backend Development
Usually, the users see the front end of an application. But, the server-side development is the back-end. Mainly, the back-end of a Mobile application is used to store, secure, and process data.
To send information for processing on the server, you need back-end development. For example, user information processing like Signups, logins, messaging, storing data, and more essential tasks happened in the back-end of a mobile application.
Some mobile software doesn’t need back-end development. That software can be a calculator, camera, notes, voice recorder, and so on.
Because these apps can run on the mobile without any internet connection, and they don’t need to store or retrieve data from the server. But, Amazon, Netflix, or any internet-dependent application must need back-end development.
API- Application Programming Interface Development
As I said before, many apps don’t need the support of the back-end. But the number of such applications is few. Most of the applications need connectivity, and they constantly communicate with servers. It means they use the back-end, web service, or APIs.
RestAPI is a standard and top-rated tool for building APIs. With it, anyone can interact and connect easily to a remote cloud data server.
Using Common Architecture
If you are going to build your own API, then prefer the standard architecture. However, most of the developers use a usual architecture for a general baseline. Thus, you can speed up your mobile API development process.
You may have heard about the four different types of common architecture. They are as follows:
- Pragmatic REST
- Web services
- And hypermedia
But, pragmatic REST is a top-rated and most popular for mobile app development.
Focusing on Security
It is essential to focus mainly on security from the beginning to the end of the development. You can use readymade API or can build your own but must ensure security measures.
Security is a crucial fact in mobile app development and a must-have component for developers.
Before invoking a web-based API, developers need access control mechanisms, privacy control, and secret keys.
Today, API standards like OAuth2, TLS, and Open ID are top-rated APIs that also make integration easier.
Everyone wants to be sure whether a product is properly working or not. So, you must find out the problems of your product before your company releases it.
In the quality assurance stage, ensure that the app is working well.
See if the app is compatible with different size screens and a variety of platforms. Is it working well on each?
You can also check the quality by providing beta testing. App’s Beta versions are only for selected customers who can test the app and give feedback.
Protecting your client’s information is a must. So, ensure that all info is in a safe combination. Also verifies the performance of navigation, menu, and buttons.
Testing the App
In the stage of Quality Assurance testing, there are more things to do. Your developed mobile application must go through a bunch of testing stages.
This is the stage where you make your app more stable, usable, and secure. You have to do this step-by-step. The steps include performing testing, recording testing results, tracking, and fixing, then retesting again.
It is crucial for the quality of the application as it determines the reliability, stability, and usability of the app before deployment.
There are two types of testing for mobile app development: one is manual, and the other one is automated testing. Besides, there are several aspects to perform inclusive testing. After finishing a complete testing cycle, your app will be ready for deployment.
Your app should go through the following testing cycle:
- Functional Testing
- Performance Testing
- User Experience & Interface Testing
- Documentation Testing
- Security Testing
- Configuration Testing
- Platform Testing
- Recovery Testing
- Beta Testing
- Certification Testing
Every user will react differently to your application. It is common, and they will use the app differently. That is why it’s important to ensure that the app is functioning well.
Here, the tricky question is how you will know the behavior of the users? Like the question, the solution is also complicated and tricky. However, you have to go in a complex way for the good of your application.
If you can test your application with as many users as possible, you can ensure 100% (one hundred percent) functionality. When many users report bugs, they put different data. In this way, you can have a complete scenario of defects.
In addition, if you are developing an app for iOS and Android platforms, you should include a feature comparison in the functional testing. Some functional testing facts you must include in your mobile app development testing are:
- Installation & initialization for all the channels
- Business features testing
- Testing fields
- Testing parameters
- Testing user feedbacks
- Any interruptions
- Testing device resources
- Possible updates for all channel
After passing the essential criteria, test the app’s API and back-end. Mobile app performance tests mainly depend on these two. Also, check the consistency of the app with performance testing.
Consider the following points while testing the performance of your developed mobile app.
- App’s performance testing under a high volume of data
- Testing the speed of the app
- Testing the stability to see how it behaves
- Testing the response time of the app
- Testing the battery usage to ensure zero percent (0%) battery draining of devices
- And testing to find any memory leak
UX & UI Testing
UX/UI is the user’s main interacting point. That is why you need to perform inclusive testing of UX and UI. See if UX/UI is performing as per the client’s requirements or not. Make the user interface easily accessible for the users by testing it well. While testing UX and UI, you need to consider the following facts.
- Test the visual interaction, navigation, and flow of the application
- Test for design consistency, fonts, icons, and so on
- Test the color scheme, design, and the entire look
Documentation testing in the mobile app development process includes testing the cases, requirements, and plans. In addition, checking screen layouts, specifications, and client needs is also crucial in this case.
You should control the whole development process through guidelines. So, it is necessary to ensure that your developers followed the guidelines strictly or not.
While talking about testing the security, this is the time you should go for special testing. It is because mobile app security is the top concern of any enterprise. A little vulnerability or security risk can lead the app to hack.
Most companies hire experts for their mobile app development security testing. It is because the QA and the development teams can perform minimal testing through app development.
You should use a trusted mobile app development service from the beginning of the development. For example, iOS apps provide the Keychain feature for storing a user’s account details. So, make sure you have chosen efficient services and their features to ensure no data leakage.
Configuration testing in mobile app development comprises app configuration for all the devices. It is also necessary to check the ultimate performance of the app in this stage. See if the app is missing any features that don’t work with specific devices. Also, perform the following tests:
- Browser compatibility
- Database configuration
- Network connectivity
- Operating system configuration
Platform testing is inevitable for mobile application development. This is because there are always new devices coming with the change of technology. However, these technologies bring new features with new hardware.
So, make sure your app will be compatible with future technologies and the changes. Then perform platform testing by considering the following aspects.
- Application compatibility for different operating systems
- Client-side browsers compatibility
- App testing for device compatibility through multiple devices
- Cross-platform mobile applications testing
- Testing cross-browser compatibility
There are no such applications that don’t face unwanted errors or failures. The error can occur from hardware or software. So, every mobile application must have the power to recover from any kind of error. Therefore, you can’t deny the importance of recovery testing in your mobile app development.
Testing certification checks if the app meets the standards of app stores like Google Play or Apple App Store. This is the final and very crucial for any mobile app development process. Things you might consider in certification testing are:
- Checking the licensing agreements of app stores
- Checking for any violations and so on
After passing all the test cycles, now it’s time for your application to be reviewed. You will create a report for the full testing in the review process. This will help you get a better understanding of the errors and failures.
Include the following things in the review document to prepare the best review from all sides:
- Information about all the tested devices, OS, and Versions
- A complete summary and test results
- Total number of tests
- And the conclusion
Deployment and Maintenance
After finishing all the functionalities and formalities, the last step of mobile app development is deployment. That means your mobile application is ready for uploading to the app stores. For example, if you developed an iOS app, you will need to upload that to the Apple App Store. But, it is an Android App, then you will have to upload it to Google Play Store.
While uploading an app to the app stores, you will have to input some metadata about the app. The metadata for app submission are as follows:
- App Title
- App description
- App’s category
- Focus keywords
