### 5/5 — Nearly perfect

*2026-07-29*

Really appreciate that the devs were able to fix a bug I reported! 

It would be nice if there was a way to mirror the compass about the vertical axis to make the numbers increase in the counter-clockwise direction.

**Developer response:** Thank you for deciding for our app. The bug was fixed (we hope). Please let us know, if you want more features. Displaying a background image from the gallery is next.

### 4/5 — Decent for what it does

*2026-01-13*

I tried & deleted 2 other protractor apps before this one.

This has a protractor where all 360° are visible. Zooming in can be done by holding the dot in the center and pinching (not sure if that info was in the popup I immediately closed). There’s even a way to reset to the original view.

The camera can be turned on/off, and even paused so you don’t have to hold your phone still while measuring angles which is nice.

The app rotates with your phone, but *the camera has a bug* that rotates the wrong way.

The app does not automatically read angles according to your phone’s orientation, nor does it convert to radians which I don’t care for, but it does what I want without pushing ads :)

**Developer response:** Thank you for deciding for our app. The bug was fixed (we hope). Please let us know, if you want more features. Displaying a background image from the gallery is next.

### 1/5 — Not what I wanted.

*2025-11-07*

I wanted to measure angles on a boat photograph. Did not find a way to do it with this app. So, gone

**Developer response:** Hi, we will release an update that allows measuring angle in images from your gallery. Thank you for you input that made us do this.

### 1/5 — Hängt sich sofort auf

*2024-10-03, version 1.01*

Gibt keine Bedienungstipps und hängt sich sehr schnell auf - völlig unbrauchbar

### 5/5 — Macht genau, was es soll

*2024-08-31, version 1.01*

Top. 
Einfacher Winkelmesser mit Kamerafunktion.
Das Bild kann man einfrieren und in Ruhe messen.
