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. ## Key features - Measures angles - Measures joint range of motion - Assesses joint injury extent - Predicts recovery speed - Easy to use interface ## Recent user reviews (10 of 34) All indexed reviews: https://appshunter.io/ios/app/goniometer/id406942245/reviews.md ### 1/5 — Absolutes gibberish *2025-10-05* No real instructions. First angle doesn’t match what “instructions “ show, not level with phone. Totally useless. Don’t waste $4.99. ### 1/5 — Can’t get it to work *2021-09-06* I can’t read the instructions, ie the start and end, can’t see which to press and thus far cannot figure out how to use this. For me, was a waste of money. ### 1/5 — This app doesn’t work *2021-07-01* This app is a scam. I followed the instructions and it does not work. ### 1/5 — Need better instructions *2019-06-27* The info page is okay but you still need to show an example of the numbers mean. Do I subtract the end measurement?? This wasn’t worth $4.99. ### 1/5 — Limited functionality *2019-06-19* Waste of money. ### 1/5 — Waste of money - DOES NOT WORK *2019-03-23* Seems like the developer has not updated the app with iPhones updates. This should be removed from the App Store unless it becomes functional. Do not buy until new reviews mention it has been updated. ### 1/5 — Doesn’t work *2019-03-11* Not worth the money if I have to figure out results after the measurements. The Goniometer should start out at zero and then give number after you measure. ### 3/5 — A strange flaw *2018-10-20* When I touch start, it shows the beginning angle, then when I hit stop, it shows the ending angle. Do I have to add the numbers (or subtract) to get the total and turned. This shouldn't be necessary, unless I'm missing something. 'Start' should be set as zero, no matter the original angle, then rotating the phone would show the total and turned, regardless of original orientation. Did I miss something? Ed ### 2/5 — Difficult to use on yourself *2018-08-02* I had hoped to measure my own knee ROM, but although you can hit the start button, it’s super difficult to find the end button when the screen isn’t in your line of sight. Would be great to be able to click the home screen or a side button to start/end ### 1/5 — Needs update for IPhone 7 iOS *2017-11-17* Needs update for iOS 11.3.3 !!!!! 😡 ## Frequently asked questions about Goniometer ### What does this goniometer app do?
