## What is Digital Angle Finder?

Digital Angle Finder is an app for precise measurement of angles, simply by moving your device. The "Digital Angle Finder" app measures the angle of the device, using the accelerometer and gyroscope.

Just place your device against two surfaces in turn and "Digital Angle Finder" will give you the angle between them. In the protractor mode you can also determine the angle between lines on a plane: in order to do so align the edge of your device alternately against the sides of the angle.

The accuracy of angles measurement is rather high: the error is only one degree!

You'll appreciate the ability to save the measurement by taking a photo with the measured angle recorded on it. We are sure that you will like the design of this app.

Digital Angle Finder is an app that adds a new feature to your device which you have never imagined!

## Key features

- Precise angle measurement
- 3D angle measurement
- Protractor mode
- Save measurements with photos
- High accuracy (1-degree error)

Amazing! An app that does just what it claims, without annoying ads / up-sells, and without tracking. Five stars.

### 2/5 — Nicht das was ich gesucht habe.

*2025-08-23*

Dauert auch etwas lange bist das Ergebnis angezeigt wird.
Schade dass es nicht auch eine Wasserwaagen Funktion hat.

### 1/5 — Junk

*2025-05-30*

Horrible app doesn’t work everything is 172 degrees

**Developer response:** We strive for high accuracy in angle measurements, and the error should generally not exceed 1°. We suggest taking a look at the instructions or the short demo videos included in the app to ensure proper usage. And, please check the measurement mode, as the program has two modes: measuring plane angles and measuring dihedral angles in space. In our experience, most issues stem from selecting the incorrect mode. If you’re still experiencing an issue, please reach out to us via the feedback option available within the app.
