Android app development: Kotlin native or cross-platform

Android app development has two main paths: native via Kotlin / Jetpack Compose, or cross-platform via Flutter / React Native. Native delivers the best performance and the deepest Material You implementation. Cross-platform delivers parallel iOS + Android launches.

Flutter is ideal for most products because shipping to two stores from one codebase is fast. Tablet, ChromeOS, foldable support, or very specific native APIs make Kotlin native safer.

Play Store offers a more flexible launch flow than App Store. Internal testing (up to 100), closed testing (groups), open testing (public but flagged 'beta'), and production track — we use all in our process.

We recommend a 1–2-week beta phase before launch. Real-device, real-user issues are caught and fixed before production, so post-launch crash rates stay low.

Material You generates a dynamic color palette from the user's wallpaper on Android 12+. Even with brand-protected design, it can be used as a dynamic accent — the app feels personal on the user's device.

We support this by default; your brand color stays protected, and dynamic theming activates as an option.

Android has very high device variety — low-RAM devices, high-end, foldables, tablets — all must run in one app. We measure performance per device tier with Firebase Performance Monitoring; we report cold start and frame drops.

Crashlytics is active on the last pre-launch build. We also use Firebase Remote Config for fast post-launch flag toggles; critical for A/B tests and gradual rollout.
