I used it to get an angle for my compound mitter saw. I drew the line on the board at the angle I needed and use this app as a protractor. Then set up my saw and put the board on it. The line and the saw where exactly the same. I haven't used it in to many situations yet but if ever lets me down I will change my review. But I thinks it's worth money. I even tried it where I new it wasn't going to work like a compass just to see if you needed any special external signal and it still worked .This is important to me cause I work in a Steel Mill in basements and places with no reception at all. ### 5/5 — It's great *2013-05-08, version 1.3* I use it all the time while reverse engineering parts and testing equipment. ### 5/5 — Drawing Triangle *2013-05-04, version 1.3* Отличный эклиметр ! Пять баллов? ### 5/5 — Brilliant!! *2013-01-04, version 1.3* Needed to be able to cut some timber at various angles for a DIY project, and this was an absolute life saver. Easy to use and brilliant. Highly recommend it ### 5/5 — Great *2012-12-15, version 1.3* Good well designed app ### 5/5 — Il falegname *2012-11-01, version 1.3* Ottimo strumento di lavoro, se facesse anche il caffè sarebbe ottimo!!! ### 4/5 — Ist gut *2012-03-30, version 1.2* Muß man nicht haben aber sehr sinnvoll für unterwegs ### 5/5 — Beautiful app *2012-03-20, version 1.2* A beautiful and incredibly useful app. Very accurate, easy to use - works perfectly on the iPhone 4. ### 5/5 — Ok *2012-03-05, version 1.0* Utile ! ### 4/5 — Molto utile *2012-03-04, version 1.0* Semplice e molto pratico da utilizzare! ### 5/5 — 👍 *2012-03-03, version 1.0* 👍 ### 5/5 — Amazing app *2011-10-25, version 1.0* I was looking for an app that took advantage of the gyro in my iPhone and I found this. It's actually amazingly accurate! I find myself measuring angles all the time now, brilliantly useful app. ## Most critical reviews (10 lowest-rated) ### 1/5 — No good on IPhone 5 IOS 6.01 *2012-11-10, version 1.3* Great looking program. Wish it worked in my hardware. ### 1/5 — Zu ungenau *2010-08-06, version 0* Nicht mehr als ein nettes Spielzeug, um das Gyroskop vom Iphone 4 zu testen. Ergebnis des Tests: Als Winkelmesser unbrauchbar, zu ungenau. Bei einer Drehung um 360 Grad fehlen plötzlich trotz vorheriger Justierung bis zu 5Grad. Ob das jetzt ein Ausrutscher bei meinem Gerät ist, kann ich nicht beurteilen. Jedenfalls ist damit das Thema Winkelmessung mit dem Programm und dem Iphone erledigt. ### 2/5 — Download, Smile, Delete. *2010-08-18, version 0* Nice to check the iPhone4 gyro. Once happy for 2 minutes, delete. Ruler does not work and cannot measure anything. The rest is fun. ### 3/5 — Ruler is not accurate on iphone6+ *2015-06-30, version 1.5* Otherwise I have no complain. ### 3/5 — iSetSquare *2012-05-08, version 1.2* Works Okay on iPod/iPhone - BUT not on iPad. It will not load onto the iPad. ### 3/5 — Wer lesen kann, ist klar im Vorteil *2010-07-24, version 0* Ha, es ist ein Unterschied, ob man IOS 4 oder ein Iphone 4 hat. Es funktioniert nur auf dem Iphone 4. Nicht auf der 3er Reihe. Also aufpassen, sonst ist das Geld weg und es passiert nichts. Vielleicht kommt ein Update für die 3er Reihe. al abwarten ### 4/5 — Set Square *2013-03-20, version 1.3* Love it. Need to learn more about it but that will be fun. ### 4/5 — 👍 *2012-12-22, version 1.3* Hab's schon oft benutzt und hat immer funktioniert! ### 4/5 — Set square has a few problems *2012-11-16, version 1.3* I like the presentation and the accuracy it shows and can see this is useful in a number of ways. I have a proble, switching between inches and centimeters. It get stuck in cm and will not switch back to inches. Perhaps it favors metrification. ### 4/5 — Manchmal ungenau... *2012-04-06, version 1.2* Diese App ist echt klasse! Sie misst Winkel auf meinem iPod touch 4 fast immer mit einer Genauigkeit von 0,1°! FAST immer... Denn manchmal ändert sich der Winkel langsam, obwohl ich den iPod gar nicht bewege. Könnt ihr diesen Fehler bitte beheben? Dann werde ich der App auch 5 Sterne geben. ## Most praised reviews (10 highest-rated) ### 5/5 — Serrage de culasse *2025-08-18, version 1.7* Utilisé pour un serrage angulaire de culasse. Très pratique et simple. Hyper précis. Économique : 2€ pour une précision parfaite contre 120€ pour un outil électronique ou 20-30€ pour une chinoiserie sans précision. Donc parfait cette petite application, pas trouvé d’équivalent mis à part la boussole (mais beaucoup moins pratique) ### 5/5 — Validissima *2022-08-22, version 1.7* Una delle migliori app del genere. ### 5/5 — Erstklassig!!! *2017-12-12, version 1.7* Die Idee und die Grafik sind echt super! Die Genauigkeit ebenfalls. Dafür muss man die App jedoch auch wie vorgesehen benutzen, nämlich mit flach liegendem iPhone. Genau wie „Clinometer“ aus derselben Schmiede eine Augenweide und ein echt praktischer Helfer! Unter anderem zählt die App komplette Umdrehungen. ### 5/5 — Footwear fitter *2015-06-03, version 1.5* A very versatile goniometer that works in both the horizontal and vertical planes. Easy to use by a lone practitioner on a disabled patient. ### 5/5 — Awsome *2015-02-21, version 1.5* Perfect! Just what I needed ### 5/5 — Love the app *2014-11-26, version 1.5* I would say this app would be especially interesting to those who love to see gyro sensor in action. ### 5/5 — Great tool *2014-11-23, version 1.5* The developer has done a marvelous job developing this great tool for students and engineers. They know graphics well as well as precision work. ### 5/5 — Geodreieck *2014-11-01, version 1.5* Top App! ### 5/5 — Great *2014-10-23, version 1.4* Phantastic app, now updated for iPhone 6. ### 5/5 — Semplice e preciso *2014-07-20, version 1.3* Fa quello che deve, precisa, semplice da usare e anche bella da vedere, complimenti! Fossero tutte così le app... --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
