appamass - Tech Stack
Developer Studio for Mobile Apps, Web Applications & AI Agents
We're building scalable iOS, Android and Web applications.
Modern. Scalable. Uncompromisingly efficient.
We rely on a proven technology stack that – implemented correctly – combines maximum performance with minimal technical debt.
Our architecture is based on an efficient single codebase strategy for mobile and web as well as the native integration of AI agents into the business logic.
The result: We develop faster, maintain easier, and scale more cost-effectively than with separate setups. Up to 60%–80% code sharing between platforms significantly reduces costs and time-to-market.

Mobile App Development with React Native & Expo
We develop iOS and Android apps from a common codebase – used by companies like Meta, Tesla, and Amazon. The native applications feel 100% native – and behave that way, without compromises in performance or user experience.
Market Standard & Security: We rely on the industrial standard supported by technology giants like Microsoft and Shopify. This guarantees a stable, future-proof ecosystem as well as maximum technological independence.
Native Performance: Thanks to native UI components and the Hermes Engine, React Native apps achieve true native performance: smooth 60 fps, direct access to hardware like cameras, GPS, and biometrics, as well as short startup times.
Expo – The Modern Way: As a framework, we rely on Expo, the leading ecosystem for React Native. We use Expo not as a simple building block, but as a professional tooling layer in the managed workflow. This gives us direct access to native modules without getting lost in complex Xcode or Android Studio configurations.
Cost Efficiency: Instead of financing two separate teams for iOS (Swift) and Android (Kotlin), we develop the business logic centrally. This typically reduces initial development costs by 40% to 70%.
Battle-Tested Libraries: For standard functions like navigation, animations, maps, or biometrics, we rely on libraries used billions of times and maintained by strong communities or companies like Software Mansion.
Maintenance Advantage: Errors only need to be fixed in one central place. Updates occur synchronously on all platforms, significantly reducing ongoing operating costs.
No Vendor Lock-in: We consistently rely on open-source standards. Should a library no longer be actively maintained, established alternatives are available. You remain independent of the proprietary code of individual providers.
