What is mobile app development process?


Discovery Stage

First of all, our specialists do business analysis. We conduct market research, define your target audience and find solutions to solve the users’ problems. This approach considers all potential goings-on and provides financial benefits for products.



Product development begins with UX research. Our designers study products on the market and do analysis. This way, we can see the weak points in competitors’ products to give your product advantages.


UX Prototyping

Our designer makes mindmaps and wireframes. This stage allows us to create and test prototypes to get a clear picture of a future app and avoid not working solutions.


UI Design

When you approve wireframes, it is time to add ‘life’ to the app. Colors, fonts, animations, typography, infographics — after that we can start mobile app development.



Our frontend and backend developers have incredible technical expertise and provide proper mobile app development services. We divide the process into sprints to present intermediate builds to you. So you will get all updates in time.



We conduct both automatic and manual testing in order to find and fix all possible bugs before the release. All to make your product function without interruption.



We release your app to stores under your developer account, considering all the requirements and guidelines. We know how to get approval from Apple and Google testers.



To make sure that all bugs are fixed and the product works steadily, we provide post-launch support and further scaling. If necessary, we offer ongoing development to add features after the release.

What our clients say
Roman Chistyakov
Founder of SAORSA startup

We worked with web and mobile app development company Brivian on the Saorsa project. The team was very good at communicating, responsive and friendly during the whole project. At all stages of development, the guys showed intermediate results and offered their solutions. Team took care to make the app convenient for the end user. They have extensive experience in mobile development and know many nuances which the startupper may not know about. This was very helpful.

Derek Distenfield
COO, CFO & Co-founder of Gsdvs

I came with a cryptocurrency app request and Brivian was the perfect solution to build the utmost viable platform. They deliver excellent quality services and are customer-friendly. The team`s commitment to driving results and incredible technical expertise encourages long-term partnership. Highly recommend!


What about fixed price mobile app development?

We work on projects according to the T&M model. It makes the development process more flexible than when you use a fixed price model. You can adjust the scope and workload anytime. The T&M approach will allow us to plan additional sprints if we need to expand functionality or make design changes.

What happens after the release?

In the MVP mobile app development, when the product is released, you need to start collecting feedback from first users. What they liked, which features they would like to have, and what they didn’t like. Based on feedback we can improve your app. Then you get the feedback again and again and improve the app step by step.

Can I get post-launch maintenance?

Of course. To ensure the stable operation of the app, we need to monitor and support it. After release, we guarantee you to devote developers’ hours to fix bugs and add new features when required.

What is the difference between native and cross-platform mobile app development?

Native apps are created specifically for iOS and Android platforms. Both apps have absolutely different code and the development requires different specialists. Cross-platform apps have a common codebase, thus, this code can be used for both platforms. Such approach takes less time and money than native mobile app development.

What is custom mobile app development?

Custom mobile app development means that we will build the app responding to all your needs, budget, and technical requirements. In other words, whatever your mobile app development requests will be, we’ll build you an awesome mobile app developed specifically for your business needs.

How much does cross-platform mobile app development cost? What about native mobile app development?

You come to us with ideas and budget expectations — according to these parameters we offer different solutions. Approximately it will be:

- for cross-platform mobile app development — 2 months and $30,000
- for native mobile app development — 3 months and $45,000

P.S. Please note that this estimate is based on limited information. You can get an accurate estimate of the project by contacting our managers.

How to control a remote mobile app development team? Who will manage the project?

Don’t worry about it. For each project, we provide a project manager who will be in touch with you during all stages of mobile app development, will solve problems, and keep you in the loop.

Can I be sure there won’t be problems with releasing the product in the App Store and Google Play? How many of your projects are in stores now?

The Brivian team has extensive experience in publishing products to the App Store and Google Play. We released over 80 apps in the stores. By following the guidelines from Apple and Google, we know how to pass the verification stage.

I have a web app and want to make a mobile one. Can you do this?

Yes, it is possible. For example, if the app is created on React, and mobile app development will be on React Native, in most cases we can reuse Redux (open-source JavaScript library).

If there is an API that we can aim at, it will be easier to estimate the time needed to develop a mobile app.

Who is on your mobile app development team?

There are many key roles in creating a project: UI/UX designers who will design the interface of your application, front-end and back-end developers who will write the code, QA engineers who will check this code for bugs, and, of course, a project manager who will manage the whole process.

Which technologies do you use for mobile app development?

Kotlin, Java, JavaScript for Android mobile app development and Swift, Objective-C, JavaScript for iOS mobile app development.

Young startups or large enterprise mobile app development?

We are free to work with both large enterprise projects and MVPs for startups.
