# Pluto Controller vs ISS Detector

The clearest difference is rating: ISS Detector at 4.6 against Pluto Controller's 4.0. ISS Detector also leads on ratings volume (729 vs 8). Pluto Controller's advantage is in-app purchases (none vs 13) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

Both are free to download. ISS Detector sells 11 in-app purchases, starting at $0.99 per month. Pluto Controller asks for nothing beyond the download.

ISS Detector holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: ISS Detector has 729 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 75% of Pluto Controller's written reviews are positive against 55% of ISS Detector's, so the app with the better star average is not the one people write more warmly about.

Pluto Controller ships an update every 2 months, ISS Detector monthly. The most recent releases landed on October 24, 2026 and November 1, 2026 respectively.
