Heavens-Above

Track the ISS and satellites with precise sky predictions

Heavens-Above turns a casual glance at the night sky into a guided tour of orbiting spacecraft, satellites and comets, all backed by data that feels both authoritative and easy to use.

The centerpiece is the live sky chart, which shows in real time what is currently above your head. You can pan around, change the time, and immediately see where the International Space Station or other visible satellites will appear. The integrated tracker makes things even simpler: point your device at the sky and the app helps you identify that mysterious moving light.

Pass predictions are where Heavens-Above really shines. It delivers highly accurate forecasts for ISS flyovers, bright satellites and amateur radio satellites, complete with detailed orbit and ground-track views. Radio enthusiasts will appreciate the uplink and downlink information, while stargazers can check the location of bright comets when they’re visible.

All calculations are done locally, meaning you only need a data connection occasionally to refresh orbital elements. This makes the app reliable even in dark-sky locations with spotty coverage. A thoughtful night mode with red-on-black colors helps preserve your night vision during observing sessions.

The interface focuses on clear data rather than flashy visuals, which may feel slightly technical at first, but the structured timeline view and calendar integration make it easy not to miss noteworthy passes. The free version is financed by adverts, which are noticeable but generally tolerable for the wealth of information provided.

Heavens-Above is an excellent companion for sky watchers of all levels, from beginners curious about the ISS to seasoned observers and radio amateurs who want precise, trustworthy predictions in their pocket.
