Feature parity

TrainTime runs on five targets across three ecosystems. The core experience is the same everywhere. The differences are platform idioms, not missing features.

Each watch pairs with a phone and stays in sync: Apple Watch with iPhone, Wear OS with Android, Garmin with either. A departure you track on the phone can be sent straight to the watch, and the watch reports its liveness back. The phones add saved SBB routes with departure reminders and an in-app light/dark theme. The Apple Watch and Wear OS can view and follow a route queued on the phone.
