A website waits for the customer to come looking for it. An app is always with them: on the home screen, with a notification at the right moment, working even without internet. Building a mobile app is the most direct route to the people who matter to your business.
What mobile app development by TsarWeb includes
We cover the whole journey: from the idea and the design, through development for iOS and Android, to publishing on the App Store and Google Play and the care that follows. We work both with native technologies and with cross-platform ones like React Native and Flutter, when a single code core for both platforms is the smarter choice.
UX/UI design
We design every screen and every tap. Design that follows the habits of iOS and Android users rather than fighting them.
Development for iOS and Android
Native or with React Native and Flutter, depending on the project. We recommend the technology that delivers the best result for the budget, not the one that is most convenient for us.
Backend and API
The app is the tip of the iceberg. We build the server side, the database and the APIs that power it securely and quickly.
Testing
We check the app on real devices, different screens and weak networks. Your customers meet a finished product, not a beta version.
Publishing to the stores
We take on the entire process of launching on the App Store and Google Play: accounts, requirements, descriptions, screenshots and approval.
Support and updates
New versions of iOS and Android come out every year. We keep the app compatible, secure and evolving together with your business.
What apps we create
- Business apps for customers. Loyalty programs, orders, bookings and services: everything that keeps the customer with you. That is how we built LoyalPocket, a loyalty platform with separate apps for merchants and for end customers.
- Internal tools for teams. Apps that replace paper and chaos in fieldwork. Shopper-X is exactly such a project: a field app with offline mode that works even where the network runs out.
- Apps for an existing platform. Do you have a working website or system? We add a mobile app that connects to them and gives users faster, more convenient access.
- MVP for startups. A first version with the most important features, to test your idea with real users and investors without burning through the budget.
See our projects for more detail on how these solutions look in practice.
How the project unfolds
- Conversation and quote. You tell us the idea and the goals. Together we define the scope and within a few days you get a fixed quote with a timeline and a price.
- UX/UI design. We design the screens and the user journey. You see and approve how the app will look before development begins.
- Development. We build the app and the backend in short stages. You get test versions on your own phone and follow the progress in real time.
- Testing and publishing. Final tests on real devices, then we take on the approval and the launch on the App Store and Google Play.
- Support and growth. We monitor stability, release updates and develop the app based on user feedback.
How much building a mobile app costs
It depends on the scope: a simple app for an existing system and a product with a backend, payments and offline mode are different projects. That is why we do not publish a general price, but give a specific and fixed quote after a short conversation. It describes exactly what you get, with no hidden lines and no surprises midway.
Frequently asked questions
iOS, Android or both?
In most cases both, with a single code core through React Native or Flutter: this way you maintain one codebase, while users on both platforms get the same quality. If your audience is only on one platform or the project requires specific native capabilities, we recommend native development. We make the decision together, after we understand your goals.
How much does an app cost?
The price depends on the number of screens, the features and whether a backend is needed. After the first conversation you get a fixed quote with a clear scope. The price does not change midway through the project, unless you request new features.
How long does it take?
A simpler app or an MVP is usually ready in around 2 to 3 months. A product with a backend, more roles and complex logic takes longer. You get a realistic timeline in the quote and interim versions along the way, so you can see the progress.
Who publishes the app to the stores?
We do. We help set up your accounts on the App Store and Google Play, prepare the descriptions, the screenshots and all the technical requirements, and lead the approval process. The app is released under your name and ownership stays entirely yours.
What happens after the launch?
We do not disappear. We monitor stability and bugs, release updates for new versions of iOS and Android, and develop the app based on user feedback. We agree on a support plan that fits your needs and budget.
