How we work

Overview: Three phases from kickoff to live in the stores. We do the App Store and Play Store submission ourselves so your team does not learn the rejection rules the hard way.
Step 1 — Scope and architecture: Two-week scoping. We map screens, deep links, push notifications, in-app purchases, ATT consent, and any platform-specific APIs (Apple Pay, Sign in with Apple, Health, HomeKit, NFC, BLE).
Step 2 — Build in sprints: 8 to 14 weeks of build. Two-week sprints. TestFlight beta from sprint 2. Internal Track on Play Store from sprint 2. Demo every Tuesday with you.
Step 3 — Harden and launch: 2 weeks hardening plus store submission. Crash-free rate target 99.7%. Symbolicated crash reports wired in. App Store Review and Play Store Review handled end to end including ATT and Play Data Safety form.

FAQ

Cross-platform (React Native, Flutter) wins when the surface is mostly UI and the platform-specific features are light. Native wins when you need Apple Pay, HomeKit, ARKit, Bluetooth Low Energy, on-device ML, or the kind of UI polish that makes the app feel like a first-party Apple or Google app. We tell you which fits at the scoping call.
