A Goniometer is a device that measures angles or allows an object to rotate to a specific position. One of its most common uses is measuring a patient's range-of-motion (ROM) for a particular joint. This measurement is used to determine the extent of a patient's joint injury and the expected speed of their recovery. This goniometer is a basic app that is easy to use.

Verdict
The clearest difference is price: RateFast Goniometer at Free against Goniometer's $4.99. RateFast Goniometer also leads on update cadence (every 8 months vs every 44 months) and review sentiment (60% vs 39%). Goniometer's advantage is rating (3.2 vs 2.0) and ratings volume (39 vs 4). On ads, in-app purchases, monetization model and device support there is nothing between them.

RateFast Goniometer is free to download; Goniometer costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Goniometer holds the better App Store score, 3.2 against 2.0. That said, the two scores are not equally well evidenced: Goniometer has 39 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 39% of Goniometer's written reviews are positive against 60% of RateFast Goniometer's, so the app with the better star average is not the one people write more warmly about.
Goniometer ships an update every 44 months, RateFast Goniometer every 8 months. The most recent releases landed on September 28, 2026 and October 1, 2026 respectively.
