Mobile App Development for iOS and Android
We build mobile apps that ship, scale and survive their first year in the store. Since 2007 we have delivered over 300 products, from quick-turn MVPs to banking-grade platforms used by thousands of people every day. Whether you need a native iOS app in Swift, an Android app in Kotlin, or a single Flutter codebase that covers both, you get a team that owns the result end to end: discovery, UX, build, store submission and post-launch support. Payments through Kaspi and Halyk, integrations with 1C, Bitrix24 and amoCRM, and a fixed price agreed before we start.
What we deliver
Native iOS & Android
Swift and SwiftUI for Apple, Kotlin and Jetpack Compose for Android. When you need maximum performance, the smoothest animations and deep platform features, native is the right call, and we ship it clean.
Cross-platform with Flutter
One Flutter or React Native codebase, two app stores. The fastest, most cost-effective route to market when your app does not need heavy platform-specific tricks. We pick the tool that fits, not the trend.
Payments & integrations
Kaspi and Halyk payment flows, plus 1C, Bitrix24 and amoCRM integrations. Your app talks to the systems your business already runs on, so data is not stranded in a silo.
Built to last
Clean architecture, tested code and a warranty of up to 10 years. We design for the version two you have not thought of yet, so growing the product later does not mean rewriting it.
How much does mobile app development cost
Indicative prices. We send a precise quote within 24 hours of your brief.

Frequently asked questions
Should I build native or cross-platform?
It depends on your app. Native (Swift, Kotlin) wins for performance-heavy or hardware-intensive apps, while Flutter and React Native cut cost and time when one codebase will do. We assess your features, budget and timeline, then recommend the approach that serves the product, not the one that pads the invoice.
Do you publish the app to the App Store and Google Play?
Yes. We handle the full submission process: developer accounts, store listings, privacy declarations, review compliance and the first release. We also stay on hand for the inevitable review questions, so your launch does not stall on a rejected build.
Will I own the source code?
Completely. On delivery you receive the full source code, repository access, design files and documentation. There is no lock-in. If you ever decide to move the project in-house or to another team, everything you need goes with you.
Can you integrate Kaspi or Halyk payments?
Yes, payment integration is one of our core strengths. We have implemented Kaspi and Halyk flows across multiple products, along with international gateways when you sell beyond Kazakhstan. We handle the security, the edge cases and the reconciliation, not just the happy path.
Do you offer support after launch?
We do. Every project ships with a warranty of up to 10 years on the code we wrote, and we offer ongoing support plans for updates, OS-version upgrades, new features and store maintenance. Most clients stay with us well past version one.
