Allerdings habe ich nirgends gefunden, dass man die Messung abspeichern kann oder ein Foto davon machen kann. Man kann nur die Aufnahme anhalten und dann selbst ein Screenshot machen. Weiter wurde die App seit zwei Jahren nicht aktualisiert. Alles in allem ganz okay aber nichts wirklich tolles. Schade, der Ansatz war gut. ### 4/5 — Super app ! *2024-08-13, version 4.9.4* Très ergonomique et fonctionnelle, précise. Mais malheureusement l’app compagnon sur la montre ne fonctionne plus… Le rendu sur l’Ultra 2 ne rempli pas tout l’écran et surtout l’app ne répercute aucune mesure prise sur le téléphone… ### 4/5 — Apple Watch? *2023-08-17, version 4.9.4* This always integrated with Apple Watch, but hasn’t worked for a while. All fully updated. Any ideas? Thanks. ### 5/5 — Solar panel tilt angle *2021-01-23, version 4.9.2* Using my iPhone 11, I can set the appropriate incline angle of the solar panels on my RV’s roof, no matter where I’m located and even if the RV is not perfectly level. Voice output is an added bonus. Use the base of the phone for angle from horizontal and the side edge for angle from vertical. Well worth the money. ### 5/5 — The perfect app *2021-01-14, version 4.9.2* App works absolutely brilliantly. One big frustration though... why the need to choose degrees or percent in settings (which is quite a few taps/clicks) to change each time? Why not a major unit as it is currently and a minor unit below in smaller font for those of us who need both but don’t want to constantly be switching between both? User selectable primary and secondary units please? Indispensable app. Absolutely love it ### 5/5 — One of the best apps I own! *2020-09-16, version 4.9.2* Great piece of code! I have used this app so many times to hang things, level appliances, etc. Sooo handy and freaking cool to boot! ### 2/5 — Bad for golfers *2020-07-17, version 4.9.2* Not accurate enough at 1-4% slopes. iPhones with protruding cameras need cases with flat backs. ### 5/5 — Extra *2020-06-13, version 4.9.2* Juste ce mot pour partager mon enthousiasme pour cette application qui est depuis longtemps ma favorite en termes d'interface et de fonctionnalités. Le seul problème est que les boutons font une sur épaisseur qui fausse légèrement la mesure d'inclinaison mais on peut calibrer l'appli et donc compenser cela ! ### 5/5 — Breitling great for not $7500 *2020-02-11, version 4.9.2* Love this app, used it for everything imaginable for many years. Nice that it was developed by the guy who invented Breitling chronometers! ### 5/5 — Perfect for golfers using Aimpoint Express *2020-01-16, version 4.9.2* This app is perfect for golfers using Aimpoint Express to gauge the slope of greens. AE recommends a 9" Husky Digital level the costs around $60, but a larger iPhone (I use a 6+) with this app is just as good and far more portable. Love that you can read both axes (left/right and uphill:downhill) at once without moving phone. Since I always have my phone with me, I'm always ready to calibrate/double-check my feet read when on a practice green or during a practice round. Just make sure you have it set to display % slope, not degrees, for Aimpoint Express. ### 3/5 — Русский язык! *2019-09-29, version 4.7* Уважаемые разработчики! Сделайте поддержку русского языка! ## Most critical reviews (10 lowest-rated) ### 1/5 — Does not work with Apple Watch. I want a refund! *2025-06-04, version 4.9.4* Does not work with Apple Watch! ### 1/5 — Waaaaaay too complicated *2022-11-26, version 4.9.2* This thing is way too complicated to calibrate and to read. The read out is absolutely stupid. I do not recommend this at all. ### 1/5 — Rotation écran *2022-11-20, version 4.9.2* Sur iPhone 8 ios16.1. Lors de la rotation du téléphone la moitié de l’écran est visible. ### 1/5 — Needs a better calibration system *2022-06-17, version 4.9.2* Very hard to trust the readings without calibrating with a bubble level first. ### 1/5 — Waste of $1.99 *2021-05-05, version 4.9.2* Instructions basically say “This is self explanatory.” Paid $1.99, tried figuring out how to get a slope for about 10 minutes, gave up and deleted it. ### 1/5 — 왜 계속 렉이 걸리죠?ㅜ *2020-10-28, version 4.9.2* 어플 실행하면 어떨때는 되고 어떨땐 멈춰서 먹통입니다. 어플 종료 후 다시 실행해도 계속 그래요. 자세평가 할때 필요해서 샀는데 미치겠습니다. 회원 기다리는데 각도기때메 결국 못하고 다음시간에 하자고 한게 두번이에요. 무료보단 낫겠지 하고 돈주고 샀는데 왜이러나요???? 핸드폰 껐다 켜면 다시 되고 그러네요. 어플의 문제입니까 제 폰의 문제입니까....? ### 1/5 — Español *2019-12-08, version 4.9.1* Antes de la actualización lo tenía en Español, me gustaría volver a tenerlo para poder entender.. un saludo. ### 1/5 — Clinometer *2019-09-10, version 4.8* Fino all’ultimo aggiornamento andava alla grande... Ora si blocca all’apertura del l’app... Ma che combinate...? ### 1/5 — Ungenau *2019-09-10, version 4.8* Angezeigte Gradzahlen stimmen nicht und variieren, mal so mal so. ### 1/5 — No Tutorial *2019-09-05, version 4.8* Warning: There is no tutorial nor instructions on how to use this app beyond calibrating it. ## Most praised reviews (10 highest-rated) ### 5/5 — Easy *2026-08-08, version 4.9.4* A very easy and straightforward measuring tool. Does just what needed to measure steep slopes around my property. Makes this safer to know where I can take the ride on mower and the scrub cutter. ### 5/5 — Finally a real accurate tool *2026-07-04, version 4.9.4* This is the only clinometer / level tool i found on the app store that uses a two step process to properly and accurately calibrate it. All the others require you to find a perfectly level surface to calibrate. Fine at home, but out in the field thats not going to happen. Brilliant well designed tool. And an outright purchase no subscription. ### 5/5 — Updates??? *2025-09-15, version 4.9.4* Tolle App, seit gefühlten 10 Jahren. Wäre toll, wenn der Entwickler sich um künftige iOS Versionen kümmern würde, damit die App noch sehr lange funktioniert!!! ### 5/5 — Very Good with AimPoint *2024-04-14, version 4.9.4* I use it for Aimpoint Percentage to measure the green slope. I have compared it with the Aimpoint instructor tool, and it was accurate. ### 5/5 — Top *2023-09-12, version 4.9.4* Assez précis ! Plusieurs niveaux de zoom. Par contre sur iPhone 14 pro max l’image est légèrement de travers… ### 5/5 — Great app and support *2022-12-20, version 4.9.4* I’ve had this app on all my phones since I guess it came out. I know it’s been quite along time. What is interesting is apps come and go but this app has always received updates. I have great respect for developers that keep apps like this working. ### 5/5 — Great app but latest iPhone update made it all wonky. *2022-12-02, version 4.9.2* We use this app at work every day and it’s been incredible for the last 4 years. However, since the last Apple iPhone update, the app goes all wonky when you tilt your phone sideways to use the long side of it as a level. It does it to my phone and all my coworkers as well. Would be great to get that fixed. The whole level circle just gets stuck in a corner when I turn my phone in landscape. ### 5/5 — Still a solid app in 2022 *2022-06-10, version 4.9.2* Absolutely perfect for a discerning engineer — well designed, clean, no bloat, reliable 0.1 degree increments and small install size. ### 5/5 — App muito prático *2021-03-14, version 4.9.2* Indispensável e muito prático para serviços técnicos. Pena que é pago na App Store. Na play store é gratuito. Pelo menos quando compramos vem sem propaganda. Ótimo custo-benefício ### 5/5 — Nicely designed app *2021-02-07, version 4.9.2* Very easy to use and get readings. Highly recommended. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
