App Developers involved in a Project

Business Analyst

A business analyst is someone who understands your project from the very beginning. They’ll sit down with you, ask you many questions, and try to get to the root of what you want to achieve. From there, they’ll help define the KPIs of the project, create the architecture of your app, and lay out a plan for how to make your project happen. They’re always looking for ways to make things better and more efficient. And in the end, they’ll help make sure that you reach the goals that you set out to achieve in the beginning.

During the course of implementation, whenever a team member is stuck in building a particular logic or needs more clarity on a specific process, they reach out to the business analyst for clarity.

UI-UX & Graphic designer creative used on Mobile app Development page

UI/UX Designer

A UI/UX Designer plays a crucial role in mobile app development. He focuses on 3 key things: to make the app attractive, intuitive, and easy to use. He ensures that the client’s brand logo, font, and color preferences are reflected in the app’s design. By doing this, he creates a cohesive and consistent look that helps the app stand out.

In addition to the screen design, the UI/UX designer will also help in creating the other designing collaterals of the app including app store images, icons, splash screens, and much more. He adds the wow factor to the whole app experience.

App Developers

Up next are the mobile app developers! These are the people who take all of the UI/UX designs and turn them into functioning applications.

They work closely with backend developers to ensure that the relevant APIs are integrated so that the app can fetch and display the correct values.

App developers work closely with business analysts to add the correct business logic to the mobile app. This helps the app to align with the client’s vision and goals.

Project manager creative used on Website Development page

Project Manager

A Project Manager is responsible for managing the project from start to final launch. His 3 key responsibilities are ensuring: the project stays on track, client servicing, and team coordination.

A project manager manages the relationship between the client and the development team. This includes communicating with the client, capturing feedback, managing tasks, and reporting progress.

Software Tester creative used on Website Development page


Testers play an important role in making sure that apps work well on different versions of Android and iOS. They test each of the app’s functions in detail to identify any bugs or errors.

Tester coordinates with the app developers to get these issues fixed. In other words, they help make sure that your app is flawless, performs well, and is secure and easy to use.

App Development Process

It is the most basic yet crucial step of our process. This step helps us understand the vision of the client and the goal that they are trying to achieve from their application.

And if there is a situation wherein the client isn’t clear about their idea then we consult the client and help them gain clarity on their project.

In this step, we work on the documentation that will help us while developing your app. We call this document as ‘Action-event sheet’

The documentation ensures that everyone is on the same page with regard to the progress of the project. It includes database schema, special cases, notifications types, etc.

We also define the milestones and timeline for the project in it.

The designs and wireframes for each app screen are created along with the flow of the app. This is shared with the client for approval and feedback. This step also helps to define the entire user experience. The designing is done on AdobeXD.

Based on your inputs and your preferences, or your brand guidelines (if you have one), we start developing the various elements for the user interface. We prepare the deliverables which would be appealing for your clients.

We’re considered as the top mobile app development company in Mumbai when it comes to UI & UX designing. Our UI designs are intuitive and simple to use. We empathize with the target customer while designing the UI.

In this step, the team starts to code the app. We use an agile methodology for the implementation of the project. The project is implemented in multiple sprints, each having a well-defined goal. At the end of each sprint, the progress is shown to the client.

We also create a WhatsApp group with the client. Our team shares development update on this group too regularly.

All the developed units are optimized and polished to ensure consistency. Additionally, the mobile software is also optimized so that it can work properly on different versions of the mobile operating systems. 

We also connect analytics to the mobile app to track user engagement in the app.

The modules are individually tested for loopholes and bug fixes. We have defined in-house quality assurance standards for mobile app development.

Only once those standards are met satisfactorily, the app is shared with the client for final approval and validation.

After the mobile application is approved by the client, we proceed with its deployment on the Google Play Store or Apple App Store.

We ensure that the app is compliant with the protocols put forward by the respective app stores. Finally, the app is launched.

Once the mobile app is launched successfully, we enter the maintenance & support phase. In this phase, we ensure that the mobile app runs smoothly in the latest versions of the operating systems on different devices.

Our team shares the MobileAssure report which includes snapshot of the app from our testing tool. Our testers simulate different conditions (geography, OS version, network connectivity, etc.) and test the app’s performance.

We also undertake the task of fixing bugs in the application and making small changes in it based on the client’s preferences.

We engage with clients regularly through our WhatsApp support group or Google Meet session.


Our developers prioritize security by implementing encryption, secure authentication methods, and secure data storage. We also carry out regular security audits and updates that are crucial to protect user data. Additionally, we sign a Non-Disclosure Agreement (NDA) that ensures confidentiality is maintained.

The cost of developing a mobile app depends on several factors such as platform, complexity, business model, and so on. Our team will conduct requirement analysis sessions with you to understand your vision and estimate a quote for your project.

Our solution is cost effective because we use hybrid app development technology – i.e. Flutter. Flutter is a latest cutting edge techonology from Google specially used to build custom mobile apps.

Here are rough estimates for developing certain types of apps:

App typeCost
Basic Ecommerce app₹ 140000
Informative app₹ 80000
Basic Productivity app₹ 120000
Complex Ecommerce app₹ 250000 – ₹ 400000
Social media app (Tiktok clone)₹ 500000
Healthcare app₹ 350000
Basic CRM₹ 200000
Complex Business app₹ 250000 – ₹ 400000
E-learning app₹ 300000

Yes, we do offer maintenance & support services for the mobile app. Through our maintenance services, you can be assured that your mobile app will remain compatible with the latest versions of Android & iOS. Furthermore, we also provide you with updates related to functional enhancements and design improvements

The timeline depends on factors such as the complexity and features that need to be integrated into the app. We provide customized estimates after understanding your app requirements. On average, it takes around 2-3 months to develop an app.
