We build iOS apps in Swift and Android apps in Kotlin or Java. Native is our default when an app needs the camera, Bluetooth, sensors, background work or long-term maintainability, and it is where most cross-platform projects end up anyway.
Apps that pair with a device over Bluetooth LE, read its data, and send settings or commands back.
Scanning, measurement and image capture flows that need direct access to the camera and sensors.
Accounts, payments, push notifications, offline mode, and the admin systems behind them.
Apps whose original developer is gone: we audit the code, stabilise it and keep it releasing.
Reconnection, background modes and the differences between Android vendors are designed in from the start, not patched after launch.
We know the guidelines that get apps rejected and plan permissions, privacy text and in-app purchase flows around them.
iOS and Android share one written spec and one acceptance checklist, so features ship the same way on both.

Full write-up (Chinese)If the app is mostly forms and lists, cross-platform can be the cheaper choice and we will say so. If it depends on Bluetooth, the camera, sensors or background work, native is usually cheaper over the life of the app.
Yes. We start with a short code and release audit, tell you what is risky, and then take over releases and maintenance.
