BELT is being prepared for iPhone and iPad with route visualization and turbulence guidance. Basic tracking and route summaries are planned alongside optional Plus time/altitude exploration and a national forecast map. Final availability and localized terms will be shown in the App Store.
The website stays focused: useful route context, flight lookup when its data service is ready, and a clear path to the app. It does not turn a general route guide into a promise about your seat.
