It's absurd to charge a fee just to remove ads to other apps from the same developer. ### 1/5 — Can’t use existing photos. *2025-06-23, version 2.4.2* I paid the 99 cent fee to unlock the camera. Then I found out I wasted my money as you can only use the camera within the app to measure an angle, but not on an existing photo. Too bad. ### 3/5 — I k. K B *2025-06-19, version 2.4.2* I c u ### 1/5 — Garbage *2025-05-11, version 2.4.2* Garbage app ### 1/5 — DISAPPOINTED. *2025-04-09, version 2.4.2* This app , this app right just so many ads and viruses, and if your going to make this app at least make it so you can use a camera. i TRIED to use it for work and yea, didn’t work not one bit. Do better. ### 1/5 — It’s not free and hence only works if you pay *2025-02-15, version 2.4.2* It doesn’t work unless you pay. Comments with 5 stars are from years ago when the app might have been free. It doesn’t even allow you 5 secs to measure anything. Bought a real one so app will be deleted. ### 1/5 — Not useful *2025-01-01, version 2.4.2* If you try to use degree for measuring the app will force you to buy premium version and you can only use rad measure 😕😕😕😕 ### 1/5 — DO NOT USE I can’t cancel service *2024-10-22, version 2.4.2* I have tried to discontinue my service but the app won’t stop charging me. ### 1/5 — This App is Garbage 🗑️🚮 *2024-10-17, version 2.4.2* Total trash, don’t waste your time downloading it. You won’t be able to even use it unless you upgrade… This app will frustrate you more than it solves anything ### 5/5 — Highly recommend for retirees. *2024-10-09, version 2.4.2* This is an excellent-I repeat excellent, app for addressing and meeting the needs of amateurs trying to learn and hone the skills. As a retiree I recommend this highly. Dr. J. Bassett. ## Most critical reviews (10 lowest-rated) ### 1/5 — Was great before update. *2026-06-20, version 2.4.5* This used to work great before the recent update. Now it will only measure between 80-100, or 100-80. I can no longer set my telescope tripod to my latitude of 52degrees because of this. Was going to purchase but will delete instead. ### 1/5 — 不好 *2026-05-04, version 2.4.4* 這個程式一點也不好不能量度 ### 1/5 — TOO LAGGY!!!!! *2026-04-28, version 2.4.4* DID NOT WORK AT ALL ### 1/5 — Do not recommend *2026-04-14, version 2.4.4* My screen is sideways so it must be the the camera but only in this app please help me find a better app so my homework is possible when I try fixing it it goes the wrong way help ### 1/5 — Blue *2026-04-04, version 2.4.4* Don’t ask for a review three seconds after downloading the app ### 1/5 — No vale para nada *2026-02-12, version 2.4.4* No vale para nada. Dinero tirado ### 1/5 — Basura total *2026-02-03, version 2.4.4* Basura total no sirve de nada al tomar foto es una caca ### 1/5 — haven't used it yet *2025-09-29, version 2.4.2* haven't used the app yet. app asked for a review straight up, so I'm giving it one. ### 1/5 — Buy to see degrees? 😆 *2025-08-24, version 2.4.2* Don't waste your time and money. They want you to pay in order to see degrees. Garbage money grab. Booo! ### 1/5 — Only Radians available *2025-07-13, version 2.4.2* If you want degrees, you must buy the app. ## Most praised reviews (10 highest-rated) ### 5/5 — Protractor *2026-05-04, version 2.4.4* Protractor works right at finding the right angle. ### 5/5 — Good! *2026-03-28, version 2.4.4* It helped me finished my homework. ### 5/5 — Good stuff *2026-02-28, version 2.4.4* Really good stuff ### 5/5 — Giocare *2025-11-30, version 2.4.4* questa applicazione la uso per giocare ### 5/5 — Engineer *2025-11-07, version 2.4.3* Awesome tool ### 5/5 — Как удалить?! *2025-09-21, version 2.4.2* Как удалить? ### 5/5 — gooood *2025-07-17* gooood ### 5/5 — Protractor *2025-04-18, version 2.4.2* Protractor works right at finding the right angle ### 5/5 — No ads *2025-02-02, version 2.4.2* 🤪🤪🤪🤪 ### 5/5 — It’s a great app *2025-01-12, version 2.4.2* In terms of a free useable app with minimalistic advertising it’s great, the angle meter and its base features are outstanding. I jerry rig my phone on the end of a mandrel in the spindle of my lathe and use the degree finder as a dividing device. Perfect 👌🏻 Thanks! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
