An augmented-reality star map and satellite tracker. Hold your phone up to the sky to see stars, constellations, planets, the Sun, the Moon and deep-sky objects overlaid on the real sky — and track the ISS, Starlink and hundreds of bright satellites in real time. Version 1.0
Star Maps turns your iPhone or iPad into a window on the night sky. Point your device at the sky and the app overlays the stars, constellations, planets, the Sun and the Moon, and deep-sky objects exactly where they really are — so you can find and learn what you're looking at. Tap anything to identify it. Star Maps also tracks satellites: see where the International Space Station, Starlink trains and hundreds of bright satellites are right now, and find out when they'll next fly over you.
Star Maps is free to use and supported by ads. Star Maps Plus is an optional subscription that unlocks the full experience and removes ads.
Just hold your device up and aim it where you want to look — at the sky above you, toward the horizon, or even down toward objects below the horizon. Star Maps uses your device's compass and motion sensors to keep the on-screen sky lined up with the real one as you move. For the best accuracy, calibrate the compass by waving your device in a figure-8 if iOS asks, and keep away from large metal objects or magnets that can disturb the compass.
The sky looks different depending on where you are on Earth, so Star Maps needs your approximate location to work out which stars, planets and satellites are above you right now and where they appear. Your location is used only on your device for this calculation — it is never stored on our servers or shared with anyone.
The camera is used only to show the live view of the real sky behind the augmented-reality overlay, so the stars line up with what's actually in front of you. The camera image is never recorded, saved, or uploaded.
The positions of the stars, planets, Sun, Moon and satellites are computed from well-established astronomical models and current orbital data, so they're accurate. How precisely the overlay lines up with the real sky on screen depends on your device's compass and motion sensors, which can drift near metal or strong magnetic fields — calibrating the compass and moving away from interference gives the best alignment.
Open the Star Maps Plus screen in the app and choose the monthly or yearly plan. The purchase is handled securely by Apple through the App Store and applies to your Apple Account.
Sign in with the same Apple Account, open Star Maps Plus in the app, and tap Restore Purchases. Your subscription will be restored at no extra charge.
Manage or cancel anytime on your device under Settings → your name → Subscriptions. Your Plus features stay active until the end of the period you've already paid for.
Satellite orbits change over time, so Star Maps periodically fetches the latest orbital data from public sources such as CelesTrak. These requests contain no personal information — only the app asking for the current public orbit data. Keeping data fresh gives the most accurate passes and flyover times.
Yes — Star Maps works on iPhone and iPad.
