Mobile apps built for retention, not just launch.

iOS, Android and cross-platform — instrumented for the analytics that drive product decisions. We've shipped consumer and enterprise apps to global stores from our Ha Noi engineering centre.

Native

iOS & Android, done right.

For products where performance and platform-feel matter — fitness, finance, media, games — native is still the gold standard. Swift on iOS, Kotlin on Android, modern architectures throughout.

SwiftUI & Jetpack Compose — modern declarative UI.
Offline-first — sync layers that survive flaky networks.
Native integrations — biometrics, HealthKit, ARKit, NFC.

Cross-platform

Flutter & React Native.

For products where time-to-market and team economics matter, cross-platform is often the right call. We've shipped 8+ production apps on Flutter and React Native — including ByGoodieBox to the European market.

Single codebase — iOS + Android from one team.
Native fallback — drop to native modules when performance demands it.
OTA updates — ship JS bundle changes without app review.

Mobile analytics and post-launch optimization

Beyond launch

Apps that improve after release.

The first version is just the start. We instrument with Firebase, Amplitude or your analytics of choice — so the next sprint is informed by what users actually do.

Crash-free sessions — Sentry/Crashlytics with on-call rotation.
Funnel analytics — events designed around your conversion model.
A/B testing — Firebase Remote Config or LaunchDarkly.
