# Satellite Watcher vs Satellite Tracker / Radar

The clearest difference is rating: Satellite Tracker / Radar at 4.5 against Satellite Watcher's 4.0. Satellite Tracker / Radar also leads on update cadence (weekly vs every 2 months). Satellite Watcher's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Satellite Tracker / Radar holds the better App Store score, 4.5 against 4.0. Both are backed by a comparable volume of ratings — 59 and 14 respectively. Written reviews complicate that: 76% of Satellite Watcher's written reviews are positive against 67% of Satellite Tracker / Radar's, so the app with the better star average is not the one people write more warmly about.

Satellite Watcher ships an update every 2 months, Satellite Tracker / Radar weekly. The most recent releases landed on July 29, 2026 and September 28, 2026 respectively.
