Cross-platform mobile apps for iOS and Android
We develop mobile applications with complex business logic—from the initial idea and Figma prototype to publication on the App Store and Google Play, and subsequent support.
Review
What are we developing
We develop native mobile applications — separately for iOS (Swift) and Android (Kotlin). Each application is built for a specific business task: these are not template solutions or constructors.
Our applications have their own business logic, work with APIs and external systems, support offline mode, push notifications, and complex UI scenarios. After development, we publish, train the team, and stay on for support.
Swift, supports iOS 15+, all Apple system APIs
Kotlin, Android 10+ support, Google services
Node.js or FastAPI, REST, authorization, roles
Preparing, reviewing, publishing
Advantages
Why native development – not hybrid
Native code is not just faster.
That's right.
Hybrid solutions are a compromise. The native approach is the right answer for products where quality is important.
Native code works faster and smoother than hybrid solutions.
Camera, geolocation, biometrics, NFC, Bluetooth, push - no limits
iOS and Android have different logic. A native approach takes this into account
