What is Mobile App Development?

Mobile app development is a process of creating applications that supports gadgets like smartphones and tablets.

The procedure includes writing code to create and design the application.

App development is the same as other software development that includes web apps. The significant difference between app development and traditional software development is the mobile app’s ability to use native features.

For example, mobile apps can use GPS, Bluetooth, a camera, and other built-in smartphone features.

iOS and Android applications dominate the global market share for mobile app development. Most of the apps target these two platforms for their business. Several platforms can be used to develop applications per the business requirements.

What are the Mobile App Development Platforms?

The essential mobile app platforms are iOS of Apple and Android Google. iOS is Apple’s proprietary mobile OS which is built specifically for iPhones. However, Android runs on mobile devices manufactured by multiple OEMs, including Google.

Various software development kits are utilized for different platforms. Apple uses iOS exclusively for its own devices, while Google has made Android available for other industries that will meet its specific needs. Therefore, app developers have made millions of applications for both platforms.

Native Mobile App Development

This app development will create the mobile application for the particular operating system. If you intend to create an app for iOS, then the app developer will use programming languages like Objective-C or Swift. In contrast, the programming language used for developing android is Java or Kotlin.

Google and Apple provide app developers with interface elements and software development kits (SDKs). Many companies invest in native mobile app development due to the benefits they offer compared to the other types of apps. With to the booming mobile app development sector, it’s quite necessary to know about native mobile app development.


  • Apps give excellent performance on the particular OS
  • Responsive, smooth, and fast UI
  • An application has accessibility to device features that will improve the app’s overall experience
  • Marketers can make use of push notifications to increase usage and conversions
  • It is easy to configure and with minor compatibility issues

What are Cross-Platform Apps?

Cross-platform mobile applications are mobile apps that are developed to function for various mobile platforms. These apps are compatible with more than one operating system, like Android, iOS, Blackberry OS, and many more.

With this platform, a developer can create an app that runs on multiple platforms with a single code system. Companies can release products faster and with better quality. This type of app can be made available to all. 

Hence, the quality of rapid development, cost-effectiveness, and turnaround time will suit every strategy. Creating a cross-platform app will help you overcome many mobile application development challenges.


  • It supports any platform
  • It has a more extensive market reach
  • Minimal upfront expenses
  • One-time reusable source code across various platforms
  • It offers quick prototyping

What is Hybrid App Development?

This approach will define you to make single mobile apps compatible with different operating systems like Android and iOS.

Hybrid development will write the code once and run it everywhere to create an app. It has different plugins that enable unrestricted access to the mobile device’s features. Web technologies such as HTML5, CSS, and JavaScript are central to these apps while deploying the native container. The app user will get the app’s high-performance potential, interface, and functionality.


  • Enlaces UX/UI design
  • It has the short development time frame
  • It is easy to maintain
  • Cost-effective
  • Enhances performance

What is the Progressive Web App?

This term refers to the new app development method, which will bring many opportunities. It will represent the further development of an existing format of the web app.

However, Google is constantly investing in developing the software, which means that the optimization will improve the likelihood of the PWA.


  • It is a less expensive and time-consuming app development method
  • It is easily accessible via a browser, so it does not have to be downloaded or installed
  • Web APIs permit them to be installed and implemented into the deeper operating system
  • It can access the device’s native functions like camera, geolocation, push notifications, etc
  • PWAs are found through search engines and are linked through the web
  • They are based on the closed ecosystem found in various app stores

Growth of the Mobile Application in the Market

The worldwide mobile application market was about USD 187.58 billion in 2021 and is expected to grow at the compound annual growth rate (CAGR) of 13.4% from 2022 to 2030. The mobile app market includes many application types such as gaming, mobile health and fitness, music and entertainment, retail and e-commerce, and others. The presence of smartphones, rising internet usage, and the utilization of technologies like artificial intelligence and machine learning create even more demand for mobile apps. Apps, as mentioned earlier, are usually downloaded from app distribution websites such as Google Play Store and App Store for iOS.

Comparison of App Development Platforms

Native Apps

Native applications are created using tools and SDKs, which platform owners like Apple and Google provide. These apps will run natively on the platform of your choice.

  • These apps provide the best runtime performance
  • It directly uses the platform’s data via platform-specific SDKs
  • The cost of creating and maintaining the various codes for each platform is high
  • Features have to be integrated distinctly based on the platform SDK tools

Cross-Platform Apps

Cross-platform mobile applications can be written in multiple programming languages, and after that, it is compiled for every platform separately.

  • It has a single codebase for distinct platforms
  • It provides a unified user experience, even with different platforms
  • As the native libraries are not available, the dependency is on third-party open-source libraries
  • Cross-platform code is not written natively, it has to be completed and bridged, which has debugging

Hybrid Apps

These Apps are created using the latest and most advanced technologies, such as JavaScript, CSS, and HTML, and bundled as mobile applications for the needed platforms. This type of app differs from cross-platform apps by working as web containers and using the runtime browser.

  • The codebase is the same and shared in web and mobile apps
  • The web development tool is used to create mobile applications
  • It does not perform as native, but it is built using the technologies for developing the web
  • Less or no support for native devices

Progressive Web Apps

Progressive web apps did not need native or cross-platform development as they could skip app store installation and the traditional app delivery channels. They will work internally with a browser, whether it is mobile or web. The link is included on mobile as an app icon. These are web apps that also run on mobile devices.

  • It runs on the web and mobile
  • No requirement to install the app; it can be through a browser URL with a network connection
  • No support for native devices, it runs using the browser’s capabilities
  • If a network connection is not there, then there are chances that you may lose an app to a greater extent

Why Select Native App Development?

Opting for native app development will utilize the native capabilities offered by a platform. These apps can access the hardware capabilities of devices like cameras, microphones, and GPS, which will help in the faster execution of features, making building a rich user experience more manageable.

Push notifications are easier to integrate into the native development. For instance, push notifications will go via an iOS server (APNS) and Google’s Cloud Messaging platform. There are very few bugs in native apps, as the code is compiled in the native language.

Why Select Cross-Platform App Development?

The market is divided equally between the iOS and Android OS. Your valuable client can be on one or both of these platforms. Developing separate applications needs an extensive budget, and it is only possible for some companies.

If you want a great user experience across all the platforms, go with cross-platform development, as with the single development team, you can develop the apps for both platforms. It can be a manageable budget, and it saves time, though you must maintain these two apps separately.

Why Select Progressive Web App Development?

PWAs are written in older web languages like JavaScript, CSS, and HTML. These applications are only accessible via a browser. Choose the PWA if your user has uninterrupted access to the network connectivity. It solves issues through the browser without needing native capabilities like a machine learning module, GPS, and many more.

What is the Mobile App Development Process?

A mobile app development project has seven steps. This procedure may vary a little bit depending on the needs and goals of the individual solutions, but the sequence remains as follows:

Step 1: Strategy

The strategy stage will start with working on your idea. Here, you have to define your product’s goals and consider the needs for developing the application.

Your team will collect information about the market, competitors, and the targeted audience. The app developers will select the tech stack, platform, and app functionalities per your idea. In addition, the designers will come up with mobile app screens and UX concepts.

This is when you estimate an approximate cost of the application and select the monetization model which maximizes profits.

Step 2: Analysis and Planning

You have brief information about your mobile app’s market and potential users. Your programming team will analyze all this information and produce an accurate development plan. By the end of this stage, you will have your product’s roadmap.

Step 3: Mobile App Design

Now, it’s time that your team will move forward to the UI/UX design of the mobile app.

First, the designers will work on user experience. They will use an information architecture of your application. And that is the data and content in your product and how it will be viewed. This focus will always stay on user interaction.

After that, the designers will sketch the wireframes with the concept of your app design’s visual structure. While this is happening, experts are working on the style guide or design system. It includes all the information about the general look of your product, for example, fonts, buttons, etc.

Next, designers will come up with mockups of the app screen design and other visuals. But make sure that the design of your products is consistent. At last, create the app design prototypes.

Step 4: Mobile App Development

In this stage, app features are integrated with the technology you have selected for development. You will have the ready-made front-end and back-end of the mobile application.

Step 5: Mobile App Testing

In your project, after the design of your mobile app is ready and the developers have integrated front-end and back-end development, it’s time to bring your product to perfection by testing it thoroughly. For this purpose, you require QA specialists.

These experts will test the product for functionality, security, usability, and performance. They will also check the compatibility of your mobile application with different devices and different versions of the operating system. Additionally, they will test the app among real users.

Your team must be able to identify bugs and limitations of your product and fix them before launching the app development.

Step 6: Mobile App Deployment

At this stage, you can release the mobile app into the market. Select the distribution models as per the application’s operating system. For example, Apple App Store or Google Play Store, where you can share your product to access real-time users. You can also create different marketing strategies to make your app famous among users.

Step 7: Post-Launch Support and Maintenance

It is the final but never-ending step. It needs the constant improvement and support of your mobile application. You’ll need to implement updates with the latest features, improvements to the existing ones, integration of any design changes, and error/bug fixes.

What is Front-End Development?

The front end of a mobile or web application is the part that interacts with the user directly. In other words, the “applications client side”. The front end consists of everything a user will view and interact with on websites or mobile applications, such as text, photos, tables, images, and much more. A front-end developer gives the structure, appearance, behavior, and content of every part visible on the browser screen when the websites or applications are opened. The central point in front-end development is responsiveness and performance. A developer must ensure that it is responsive and work perfectly on devices of all sizes. An app’s performance must be stable every time, no matter which device is used to access the application.

What are the Benefits of Front-End Development?


The latest front-end framework and technologies give great features and performance. An organization can provide better value to its clients and customers. Moreover, existing front-end development software has more numbers and also varied offerings.

Easy to Learn

The latest and advanced technologies are used in front-end development which is simple to use in the developing phase. The learning curve is minimal.

Quick Response

A site is developed leveraging modern technologies, responses, communications, and functions speedily and seamlessly.

Highly Secure

As they use the latest technologies, they are less vulnerable to threats. Enterprise can get an extremely secure environment.

Shorter Development Period

Front-end development has achieved popularity in a very minimal period. The time which is saved can be utilized for other productive purposes.

What is Back-End Development?

The back end is also called the server side of an app or website. It will organize and store the data and ensure everything on the client side is working perfectly. Whereas the back end does not interact with the user directly, it plays an invisible role in the development phase by adding the primary functionality. With the proper back end, a front end will work properly. The back-end activities include writing APIs, creating the libraries, and working with system components without interacting with user interfaces. Hence, the core functionality of the web application is entirely managed by the back-end development.

What are the Benefits of Back-End Development?

Runs in Different Environments

Nowadays, Companies deploy websites and web applications in several environments. Many start-up businesses select sites that operate on database servers, and others install online applications in the cloud. Many companies are now merging with all hosting services to take advantage of improving scalability. Hence, the setup of a web server varies from network to network. The back-end programmers will distribute the workload server side over the multiple machines. A varying hosting environment customizes the website’s back end, which is necessary for programmers.

Share Information Faster

A back end has three major necessary elements of a website, i.e., database, web server, and application. For instance, a user can log in to her account and access the website’s user interface. A username ID and the user’s password are checked through the runtime. However, any details a user submits are processed in the back-end repositories. The back end will retrieve the data from the archive and transfer details to the web interface for an app view. Thus, the website’s back end will serve as the framework and enable knowledge-sharing.

Needs Code Logic

Many programmers now keep the website user interface and app’s logic separate as it will simplify their development and maintenance. An app logic also does the routine data processing, which is needed in each firm to incorporate the application’s domain and the infrastructure components. The back end of a website has application logic. So, developers must focus on the development of the back end and will make multiple user interfaces to access the app logic.

Adding a Functionality Utility to Front-End Development

While creating the website, programmers must write the back-end code that will include the utility of the functionality of every front end. For example, you must report the code using server-side programming languages to add the user login functionality to your app or website form. A back-end code will collect values when the user enters his login credentials and compare them with the stored login data in the databases. Hence, a website or app will only work with the quality of back-end development.

Steps to Hire a Mobile App Developer

Frequently Asked Questions (FAQs)

What are the limitations of mobile app development?

The drawback of mobile app development is that it is complicated to develop, cost, and make the developer available and the needs of its update and support.

How do apps secure data?

When we create our applications, we utilize Transport Layer Security. This protocol encrypts data and demands that the server and the application authenticate each other before exchanging any data. No data is exchanged between the app and the server if this issue occurs.

What makes the mobile app more secure?

A lack of high-level authentication will lead to security breaches. So, developers should make apps that only accept solid alphanumeric passwords. Beyond that, it is better to make it mandatory for users to change their passwords periodically.

What are the characteristics that will make the app good?

An excellent mobile app combines a great design with its functionality as the business needs it with long-term objectives as it improves business procedures and builds better customer relationships. Characteristics of good apps are well-design UI, faster loading time, strong data protection, excellent user support, and in-built integrations.

Which are the primary design areas to create a successful mobile app?

The primary design areas for mobile app development are product strategy, architecture, user experience design, and marketing.
