Works with Orbit and Satellite views too! 5) Radio frequency data for amateur radio satellites. 6) Updated descriptions for hundreds of spacecraft. Every satellite now has a description from n2yo.com. 7) Supports the latest Apple hardware and software: iPhone 13, iPad Pro, and iOS 15.

If you're new to Orbitrack, here's what it can do: • Track thousands of satellites. Orbitrack will tell you when spacecraft pass overhead, show you where to find them in the sky, and let you track them across the planet. • Teach you about the International Space Station, Starlink, and hundreds of other satellites in orbit, with comprehensive mission descriptions. • Show the view from any satellite, and see the Earth from orbit just as the “bird” sees it! Orbitrack includes detailed 3D models for dozens of satellites – see them up close from any angle! • Stay on top of the space race. Orbitrack updates its satellite data from n2yo.com and celestrak.com every hour. When new spacecraft are launched, maneuver into new orbits, or fall back into the atmosphere, Orbitrack shows you what’s happening up there, right now. Orbitrack isn’t just powerful – it’s incredibly easy to use! You don’t need an aerospace degree to become an expert satellite tracker. Orbitrack puts advanced capabilities at your fingertips, with the same intuitive touch interface you use every day. The new VR mode is an out-of-this-world experience.

Verdict

The call

The clearest difference is price: Per Watch at Free against Orbitrack's $4.99. Per Watch also leads on update cadence (fortnightly vs every 2 months) and rating (5.0 vs 4.7). Orbitrack's advantage is ratings volume (964 vs 8) and chart position (#44 vs unranked). On review sentiment, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Per Watch holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Orbitrack has 964 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 76% of Orbitrack's written reviews are positive against 71% of Per Watch's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Orbitrack ships an update every 2 months, Per Watch fortnightly. The most recent releases landed on October 22, 2026 and October 10, 2026 respectively.
