Front-end Development

Front-end development focuses on developing the user interface of the mobile application which the user sees and interacts with. It is also known as client-side software development.

Back-end Development

Back-end development focuses on developing interfaces which the user can’t see or interact with. It focuses on databases, functionality, architecture, and servers. It is also known as server-side software development.

Check out the types of mobile application development services India

You can decide what kind of mobile app you want to make. The type of mobile app will be decided based on what your app does.

The 4 types of mobile applications are:


The mobile application whose tasks remain in the foreground such that users can see them is a foreground mobile application. The majority of the tasks performed by the foreground mobile application are foreground tasks. Foreground mobile applications demand interactivity.

Visible, on-screen

High interactivity

Maximum user involvement

Example- A game is a foreground mobile application. While the application runs, the user can see the game on the screen.

However, they also have background tasks such as updates that take place in the background when the device is connected to the internet.


The mobile application whose tasks remain mainly in the background without needing user input repeatedly is called a background mobile application. The majority of the tasks performed by the background mobile application are background tasks. Background mobile applications require minimum, if any, user interactivity.

May not be visible on the screen

Low interactivity

Low user involvement

Example- Caller id detection is a background mobile application that runs automatically when the device receives a call.


The mobile application which does the majority of its tasks in the background after it gets proper user input is called an intermittent mobile application. Intermittent mobile applications require some user interactivity.

Visible for a short time

Medium interactivity

Low user involvement

Example- Audio players are intermittent mobile applications because when the user selects a soundtrack, they keep running in the background and only give notifications when needed.


Widgets are set on the home screen so users can check the desired information quickly at a glance. Widgets do not require much user involvement once they’re placed on the home screen. They interact with users by providing them with information for which they’re placed on the screen.


High interactivity

Low user involvement

Example- Clock and weather widgets are usually available on every mobile device.

Your mobile application is nurtured from start to end. We design, develop and maintain- with App Development Life Cycle.

The mobile app development life cycle (ADLC) is very crucial for any application development process. It ensures that the mobile application that is being developed is following proper protocol. Using this workflow, the end product can be delivered as smoothly and swiftly as possible. Here are the seven important stages of the mobile app development life cycle.

Research- Competition Analysis

Before we start designing your app, we gather information on other products available in the market. We take note of your requirements and the vision you have for your mobile app. Using that information, we research similar mobile applications already available in the market, and the needs of your client base and create a personalised plan for the app to make it unique, useful and attractive.

System Architecture Creation

Any application uses a similar system architecture. In any architecture model there are three layers.

Data Layer

Application Layer

Presentation Layer

GUI Design

The importance of a Graphical User Interface cannot be overstated. This is the screen the users of the mobile app will interact with. It is very important to design the GUI of the app so that it is:




User- friendly

Pointers, menus, icons, buttons, and scroll bars are some of the components of the GUI.

Verification and Modification

Once the design of the mobile app is done by the designers, it is shown to you to verify that all the requirements are being met. If there are any changes that you would like to make, then this is the time for modifications. After making the necessary changes, the design is once more shown to you. This iteration continues until you are satisfied with the mobile app design. Only then does the development of the mobile app begin.


The developers are the most active during this part. In this phase, the code of your mobile application is written. Programming languages like Swift are used to develop the code of the mobile application and all the features of the app are created. Mobile application development services in India.

Quality Assurance

During this phase, the developed mobile app undergoes testing. All the features of the app are tested by a group of potential users, experts, Quality Assurance engineers and you. Feedback is taken and all the bugs are identified. It is also checked if the app meets the standards set forth by you and TST technology.

If anything fails to meet the standards, then the required changes are made. The bugs are also removed by the developers. The improved app goes for Quality Assurance again and undergoes rigorous testing. This interaction continues until the app is working perfectly the way it was intended to.

Product Delivery

After the mobile has been approved by Quality Assurance, then proper documentation is prepared for your use. It is usually a user's manual and a comprehensive guide to everything included in the mobile app. The product is delivered to you after which you are free to launch the mobile app in the market

Client Meetings and Brainstorming

Before starting your project, it is important to understand your requirements. Team members of TST Technology will have detailed meetings with you to discuss the basic and technical aspects of what you want. This helps us to create the mobile application exactly as you want it.

Documentation- Proposal, NDA, SoW

Weekly/Monthly Reviews

App Development Life Cycle

Your mobile application development happens using this life cycle. The cycle can be broken down into 7 categories:


Before any mobile application is developed, prototypes are made so that the team members and you can get an idea of how the mobile application will look and interact after development. There are three types of prototypes which are commonly in use.Mobile app development company Ahmedabad

Paper Prototype

Low Fidelity Prototype (Wireframe)

High Fidelity Prototype


Once a prototype is approved, it goes into the designing phase. Here, user Experience (UX) is kept in mind the design is made in a manner that the users of the mobile application find easy to use and navigate.


After the designing phase is completed, the mobile app development starts. The developers write code for the front-end of the application. It is also known as client-side development. It develops the look and placement of the features such as a menu, toolbar, scroll bar, search window and related features that users interact with.


Simultaneous to front-end development, the back-end developers are working on writing the code of the mobile application which helps run the features of the application. They manage the data of the application, the process and the functionalities on which the mobile app operates.


After the development of the mobile application is complete, its testing is done by a focused user group, experts, Quality Assurance engineers and you. If any feature does not meet your standards and those of TST Technology, then the modifications are made by the developers. It is also checked for bugs and issues which are then corrected by the developers. Only after getting approved by Quality Assurance engineers can the mobile app be launched.


The mobile app is deployed as per your choice- for your business use or public use on any platform such as Play Store or App store.


Even after the app is deployed, it needs to be maintained. There are updates and new versions for the issues that arise and for supporting new technology as it emerges. The new update and maintenance of the app ensure its efficiency and reduce user complaints.
