Got Questions?

Frequently Asked Questions: Mobile Apps

Answers to key technical, pricing, and workflow questions regarding this service.

For 90% of apps, React Native or Flutter is the optimal choice because it cuts development time and budget in half while delivering near-native 60fps performance. If your app requires heavy 3D rendering, intense real-time audio processing, or deep proprietary OS features, we recommend pure native Swift and Kotlin.
