questions

Our engineers answer — not a sales team.

Talk to an Engineer →
Expo vs bare React Native?+
Expo managed workflow for most apps — faster development, OTA updates, no Xcode required for most features. Expo bare when you need custom native code. We start with Expo and eject only if needed.
How do you handle offline functionality?+
Offline-first from day one — MMKV for fast key-value storage, WatermelonDB for relational local data, optimistic UI, and background sync when connectivity restores.
Can you achieve native-level performance?+
Yes — Reanimated 3 worklets run on the UI thread, FlashList for virtualised lists, and Hermes engine. The New Architecture in RN 0.74 further closes the gap.
How do you handle App Store submission?+
EAS Submit for automated submission, all required screenshots and metadata, review process handling, and ASO optimisation included.
