Mobile app development
Tankar builds mobile apps for customers, partners and field teams, together with the API and admin panel they depend on. Most apps ship from one Flutter or React Native codebase to both stores, with offline support, push notifications and analytics where the use case needs them.
One project, not three
A mobile app is rarely just the app. It needs an API, an admin panel, notifications and analytics, and it needs the stores to accept it. Tankar builds all of it in one pod so nothing waits on a separate supplier.
Weekly builds on your phone
Every sprint ends with a build on TestFlight and the Android internal testing track. You use the app on your own device each week, which finds problems a screenshot never would.
After the first release
Operating systems, SDKs and store policies change every year. The run stage keeps the app publishable and adds the features the usage data asks for.
Typical engagements
What this service usually produces, as deliverables rather than adjectives.

Test
Automated widget and integration tests, device testing across screen sizes and OS versions, and API contract tests.
Launch
Store listings, review submissions, crash reporting and a staged rollout.
Run
OS and SDK updates, store policy changes and new features on a support plan or a dedicated team.
- Team shape
- A pod of a project manager, a designer, mobile and backend engineers and a QA engineer with a device lab.
Stack for this service
The technologies this work is usually built on, and why each one is used here.
| Technology | Why we use it here |
|---|---|
| Flutter | One codebase for Android and iOS with consistent rendering. |
| React Native | The right choice when the team already works in React and TypeScript and wants to share code with a web app. |
| Node.js | The API and admin panel are built with the app, so a change in one does not wait on a separate team. |
| PostgreSQL | One database for the app, the admin panel and reporting. |
| Monitoring and error tracking (Sentry, cloud-native monitoring) | Crash reports and API errors reach the team before they reach the store reviews. |
