FAQ

Web & Mobile App Development FAQs

What are the benefits of cross-platform (React Native / Flutter) vs. separate native apps? +

Modern React Native and Flutter architectures deliver 60fps/120fps native performance and full hardware access (biometrics, camera, GPS, push notifications) while sharing up to 90% of the codebase across iOS and Android. This cuts your initial development cost and time-to-market by ~40% and ensures feature parity on every release.

Do you handle Apple App Store and Google Play Store submission and approval? +

Yes. We manage the entire release lifecycle—including Apple Developer and Google Play Console setup, cryptographic code signing, privacy nutrition labels, screenshot/store listing preparation, review guideline compliance, and addressing reviewer feedback until your app is live.

Can your apps work reliably offline for field teams or low-connectivity zones? +

Yes. We engineer local-first SQLite/WatermelonDB storage layers with optimistic UI updates and automatic background delta synchronization—so field agents, logistics drivers, and customers can keep working offline and sync seamlessly once connectivity returns.
