The tappable mode row used a bare `clickable`, which declares no role. TalkBack read it as two pieces of text with nothing to say it could be activated, so the only way to correct a wrong mode was invisible to anyone using a screen reader - and the row had just become the only way to reach that field. Role.Button plus an onClickLabel naming the action. The label lives in the resource files like every other user-visible string. Caught by self-review against the project's own accessibility pattern in Components.kt rather than by a test; Compose UI is not unit-tested here, so this class of defect is only ever found by reading.
Look4Sat: Satellite tracker
Radio satellite tracker and pass predictor for Android, inspired by Gpredict
Track satellite passes with ease!
Thanks to Celestrak and SatNOGS you have access to over 9000 active satellites.
You can search the entire database by NORAD Catalog Number or the satellite's name.
Orbital positions and passes are calculated relative to your location.
To get reliable data make sure to set the station position via the app Settings.
The application is built using Kotlin, Coroutines, Jetpack Compose and Navigation.
It is now and always will be completely ad-free and open-source.
Main features:
- Predicting satellite positions and passes for up to 10 days
- Showing the list of currently active and upcoming satellite passes
- Showing the active pass progress, polar trajectory and transceivers info
- Showing the satellite positional data, footprint and ground track on the map
- Custom TLE satellite data import is available via Three Line Element .txt files
- Offline first: calculations are made offline. Weekly TLE data update is recommended.
