Track it, save it, share it
Follow it live, save it to your list, or generate a shareable card to show what you found.
YOUR SKY
What satellites are above me right now?
Tap once and the globe turns to face you and lights up the satellites in your sky. The ones worth knowing are named and explained, the big fleets fold into a line each, and it tells you whether it's dark enough where you are to see any of them. Real orbital mechanics, worked out on your device.
Every object has a story
Real screenshots. Real orbital data. Tap anything and this is what you get.
Thousands of Objects, Explained
Hand-written profiles on 2,800+ notable objects — who built it, why it's up there — plus live telemetry on everything.
Follow the Fleet
Watch crewed capsules and cargo freighters — Dragon, Soyuz, Progress and Cygnus — from launch through docking to landing.
Asteroids Up Close
Dozens of near-Earth asteroids on their real heliocentric orbits — sizes, close-approach dates, the works.
Everything else in orbit
Since Your Last Visit
Away for a while? The app opens with what changed in orbit while you were gone: the launches, dockings and crew changes, newest first.
When Can I See It?
The space station's next visible passes over you: when, where to look and how high it climbs. On iPhone, pass alerts give you a heads-up shortly before a good pass of the station or a fresh train. All worked out on your device. ISS tracker →
Catch a Starlink Train
Fresh launches are picked out automatically while they still fly as a line of lights. Open one to see when it crosses your sky. Trains in orbit now →
Save What Matters
Star your favorite objects or add them to a watchlist to check in on later.

Satellite tracker questions
Where is the ISS right now?
It's on the globe the moment you open the tracker, moving in real time. Tap it for its altitude, speed and the crew aboard, or press Center on Globe to follow it around the planet.
What satellites are above me right now?
Open Your sky and the globe turns to face you and lights up every satellite over your location. The notable ones are named and explained, the big constellations fold into a line each, and it tells you whether your sky is dark enough to see any. Your location never leaves your device.
When can I see the ISS from where I am?
Tap the space station and choose “When can I see it?” for its next visible passes over you: when, which way to look and how high it climbs. On iPhone, pass alerts give you a heads-up shortly before a good pass.
How do I see a Starlink train?
A Starlink train is a fresh batch of satellites still flying in a line, which lasts from days to a few weeks after each launch. The tracker picks them out automatically; open one to see when it crosses your sky.
Is this satellite tracker free?
Completely free. No ads, no subscriptions, no account required.
Does it work without an internet connection?
Yes — after the first load it works offline, and the catalog refreshes automatically the next time you're online.
Is my location ever sent anywhere?
No. Your sky uses your location entirely on your device to work out what's above you. The app keeps the last one on your device — refreshed when you open the app, never in the background — to mark you on the globe and work out when the ISS or a Starlink train passes over. It's never on our servers or anyone else's, and you can forget it any time in Settings.
What platforms does it run on?
iOS is available now on the App Store. It also installs as a full app on Android and desktop straight from your browser, no app store required.
Where does the data come from?
Real orbital data from CelesTrak, NASA/JPL, and Launch Library 2 — refreshed continuously, not simulated.
Is it to scale?
Orbital positions are exactly to scale — every altitude is drawn true, so the space station really does fly that close to the surface and the geostationary ring really is that far out. Object sizes are not, and cannot be: at a typical zoom one pixel covers several miles, so a satellite drawn true to size would be smaller than a single pixel. The dots are map markers, like a city on a road atlas.
