I bought the ad-free version because I use the app to do work things and constant ad interruptions frustrate me. So I bought the ad-free version. Then the ad-free version began constantly interrupting me while using it to ask me if I liked it. And what rating would I give it. STOP INTERRUPTING me when I’m using this app! I’m in the middle of doing a task! That’s why I bought the ad-free version! If I was OK with interruptions I wouldn’t have bought the ad-free version! ### 2/5 — Угломер *2024-03-22* нет возможности обе цу ления ### 4/5 — A bit pricey for what it is *2024-02-26* A bit pricey for what is actually givin to you. No ads 2 dollars!? Anyways. My only other gripe is that the app shows it is grey but mine is bright green with from what I can tell, there is no way to change it or access a menu. ### 1/5 — Zuviel nervende Werbung !!! *2023-08-13, version 1.17* Zuviel nervende Werbung kann keiner gebrauchen. Einbisschen ist ja verständlich aber soviel hatte ich noch nie 🙁 ### 1/5 — Crashes *2023-03-23, version 1.17* As soon as opened it crashes. ### 4/5 — App works well, but ad removal is pricey *2023-02-04* I mount my iPad in landscape next to my main computer display, and now I can instantly tell if its level or not. Its a simple app that works. As for the price to get rid of the ads? $2 is WAY too much for an app like this. $1 and less is more reasonable. I subtracted one star for the high ad removal price. ### 1/5 — Leider lässt sich bei mir nicht Kalibrieren *2022-02-04, version 1.01* Leider lässt sich bei mir nicht Kalibrieren ## Most critical reviews (10 lowest-rated) ### 1/5 — Not good *2026-07-09* Not accurate, not repeatable. And they want money for this? **Developer response:** Dear customer, the app is - if properly handled - precise down to 0.01°. For calibration to work, align the phone with a vertical or horizontal surface, let it settle and tap the calibrate button (scope icon). Them you are good to go and can achieve the highest degree of precision. And yes for an Advanced Bubble Level Tool including a fully fletched AR-Measurement Tool we do charge you - but less than our competitors are. ### 1/5 — Not accurate *2026-03-06, version 1.500* No where near accurate and can’t seem to calibrate the level straight before u measure a angle so totally out. Shame ### 1/5 — Приложение не рабочее, *2026-02-04* Просто картинка **Developer response:** Thank you for your feedback. What exactly isn't working properly? ### 1/5 — Update deserves 1 star *2025-12-28* You absolutely know why you’re getting 1 star after the most recent update. Greedy developer!! **Developer response:** Hi, developing apps in the current highly competitive environment is challenging for solo developers and requires some form of compensation. You wouldn't walk into a super market and expect things to be free, right? The core features of the app remain free to use. ### 1/5 — Use to work… *2025-08-29* Use to work fine but now I cannot get it to work. Not sure what kind of PHD I need to use this but is a level is should be very easy. **Developer response:** Hi, in case you are addressing the calibration feature. Simple approach one of the cardinal angles, let the device settle for a while and hit the calibration button (scope symbol). From thereon, if you used a properly aligned reference the app will be good to go for future uses. ### 1/5 — Not able to calibrate *2025-03-29* Tried the free version but wanted to calibrate it , button was locked as it appears to be part of the premium version. So I made the purchase….low and behold no more adds and also NO calibration button… Can’t contact support on their site since they have blocked all inquiries due to spamming… Now I have a useless app …. Do not waste your money or time on this…. ### 1/5 — Funktioniert nicht richtig *2025-01-28, version 1.37* Ich kann das iPhone hin und her drehen aber der Punkt zum ausmessen geht und kommt wie er will. Es gibt diesbezüglich keine Einstellungmöglichkeit ### 1/5 — Advertising is horrible *2025-01-20, version 1.34* No ### 1/5 — Ads make it impossible to measure *2024-12-08* I expect a certain amount of ads for a free app like this, but it’s ridiculous and makes the app unusable ### 1/5 — Almost useless *2024-10-10* Pop up in app ads render app useless. Just removed. ## Most praised reviews (10 highest-rated) ### 5/5 — Flawless Free App *2025-08-28, version 1.382* This app helps me get my iPad completely straight and level to watch when it’s on a wobbly tryone holder never let me down yet thanks ### 5/5 — Great tool *2025-08-11* I use the bubble level for my telescopes. It’s accurate and is very convenient. **Developer response:** Hi, thank you for your friendly feedback and for sharing your use case. ### 5/5 — 👍 *2025-01-13, version 1.34* 👍 ### 5/5 — Effizient *2024-07-04, version 1.26* Solide Leistung und zuverlässige Winkelmessungen mit minimaler Komplexität.       ‌ ### 5/5 — Helpful *2024-06-29* The app provides consistent and accurate angle measurements in a simple manner. ​ ### 5/5 — Awesome *2024-05-19* I use this often pretty accurate tested this app it’s good ### 5/5 — Easy to use *2024-01-28* Like since it works & simple to use ### 5/5 — This angle finder *2023-02-06* This is the best angle finder I have ever found! ### 5/5 — F GI *2022-11-24* Y Yu ### 5/5 — Bubble Level *2022-11-20* Excellent!!!!! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
