The International Space Station is one of the few genuinely spectacular things you can see with your own eyes, a brilliant point of light, brighter than any star, sailing silently across the sky. Most people never realise it passes right over their own backyard. ISS Tracker has one job: get you outside at the right moment, looking up.
No guesswork. Open the app and it tells you plainly: tonight at 9:47, look west, visible for six minutes, and how bright it will be. Then you step outside and watch it cross.
Other apps promise a live video feed and hand you a black screen. This one does not need a feed. Every pass is worked out on your own device from real orbital data, so it works completely offline, anywhere, with nothing to buffer and nothing that can go down. No black screens. No account. Just the right time to look up.
Free, forever:
- Accurate pass predictions for your exact location
- A reminder before each pass, so you never miss one
- A live 2D map of the station circling the Earth right now
Go further with Pro:
- A cinematic 3D globe with the station's real orbit rendered live
- Brightness for every pass, "brighter than Jupiter tonight," so you know which passes are actually worth heading outside for
- Beyond the ISS: China's Tiangong station, plus Hubble and other bright satellites, and Starlink launches while they're still flying in their spectacular string-of-lights formation, gone again within a week
- Home Screen and Lock Screen widgets with a live countdown to the next pass
- An education library: what you are really seeing, why it sometimes vanishes mid-pass, how a 400 km orbit and 16 sunrises a day actually work
It is not a database and it is not a live stream. Every satellite here earns its place because you can actually see it with your own eyes, not because it's in a catalogue. It is the simplest, most reliable way to answer the only questions that matter: will I see it tonight, and is it worth going out for?
Whether you have never spotted it before or you look up every chance you get, ISS Tracker turns "I always miss it" into "there it is."
Look up.
