Find out when the International Space Station flies over you and exactly where to look. On a good night it’s brighter than any star. YOUR NEXT PASS, IN PLAIN WORDS “Tonight at 8:05 PM. Look west, low.” Each pass also says how long it’s visible and how bright it is, and has a round sky chart that shows its path, from where it appears to where it fades. See 14 days of passes, and the cloud forecast for the next ones. ALERTS FOR GOOD PASSES Get a heads-up a few hours before a good pass, and an alert 5 minutes before it starts. A good pass climbs at least 30° above the horizon, or is bright and long. If two weeks have none, you get alerts for the best low passes instead. You can turn on alerts for every visible pass in the app’s settings. A Live Activity counts down on your Lock Screen and in the Dynamic Island. FIND IT IN THE SKY Hold your phone up and follow the pointer to the station. Saw a bright, moving light? Ask “Was that the ISS?” and get a straight answer. No telescope needed. WHERE IS THE ISS RIGHT NOW? See it on a 3D globe, with the day and night sides of Earth, or on a live map with the ground track of its orbit. You can add Tiangong, China’s space station, and get its passes too. WHO’S UP THERE See the crew on board, and the next launches, dockings and spacewalks. ALWAYS ONE GLANCE AWAY Widgets show your next pass on the Home Screen and Lock Screen. A Control Center button opens the sky pointer. PRIVATE AND SIMPLE No account needed. Every pass is worked out on your phone, and your exact location is never sent to us. Apple Weather and Apple Maps use it for the cloud forecast and the place name. For iPhone and iPad.

Verdict
The clearest difference is in-app purchases: ISS Tracker at none against Current Altitude + Compass's 1. ISS Tracker also leads on ads (none vs shown) and update cadence (weekly vs every 2 months). Current Altitude + Compass's advantage is iOS requirement (11.0 vs 26.0). On price and device support there is nothing between them.
