Technical FAQs & Architecture Clarifications

Common engineering questions regarding this service implementation.

Q:Why choose React Native over building two separate native apps in Swift and Kotlin?

React Native allows us to write a single, high-performance TypeScript codebase that renders native UI components on both iOS and Android. This cuts development time and cost in half, while delivering identical 60 FPS native thread performance.

Q:How does offline data synchronization work when internet reconnects?

The app reads and writes data directly to a local SQLite database on the device. A background sync worker monitors network status; when internet reconnects, it streams local queued mutations to the server and resolves any conflict tags seamlessly.

Q:Do you handle the entire Apple App Store and Google Play review process?

Yes! We manage app certificates, provisioning profiles, privacy compliance manifests, screenshot generation, store listing copy, and handle any store reviewer feedback until your app is 100% approved and live.
