Heavens-Above

What Heavens-Above is

Heavens-Above provides predictions and sky information for observing satellites and other objects. Its website lists 10-day predictions for selected satellites, daily predictions for brighter satellites, and Starlink passes from a launch, alongside a live sky view and interactive sky chart. It also presents information and charts for the Sun, Moon, planets, comets, asteroids, and constellations. The Android app includes predictions for the ISS, visible satellites, and radio satellites, plus orbit and ground-track views, night mode, and an orientation-based tracker. Users can add selected satellite passes to the device calendar. The app performs predictions locally and says it needs a data connection only every few days. The service has a free plan; the Android Pro app costs $4.99 once and removes adverts. Heavens-Above is available on Android, iOS, and the web, though the listed app-specific features are for Android. Its FAQ cautions that predictions become less accurate the further their dates are from the current time. The privacy policy says the site collects browser and visit details, including IP addresses, and may use cookies.
