ISS Detector
Gouda, Netherlands
What it is
ISS Detector helps users find visible International Space Station passes and satellite pass predictions for their location. For each upcoming ISS pass, it shows local start time, direction, highest altitude, and duration, and can notify users minutes before the pass begins. It checks the local forecast and indicates when clouds may prevent a sighting. Premium extensions add tracking for Starlink, Hubble, rocket bodies, planets, comets, and amateur radio satellites. Amateur radio tracking includes transmitter information and Doppler shift calculations, and sightings can be shared on social media. The app says it combines information from NASA, Heavens-Above, the Minor Planet Center, and yr.no weather. Its privacy policy says location calculations happen on-device and precise location is not stored on the maker’s servers. ISS Detector is listed for Android, iOS, macOS, and web. The free edition contains ads and in-app purchases. ISS Detector Pro costs $17.99 once and includes all extensions with no ads. Google Play says data can’t be deleted.
