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!

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Protractor sells 6 in-app purchases, starting at $4.99 per month. Digital Angle Finder asks for nothing beyond the download.
Digital Angle Finder holds the better App Store score, 4.1 against 1.8. That said, the two scores are not equally well evidenced: Digital Angle Finder has 237 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 56% of Digital Angle Finder's written reviews are positive against 64% of Protractor's, so the app with the better star average is not the one people write more warmly about.
Digital Angle Finder ships an update every 2 months, Protractor every 5 weeks. The most recent releases landed on October 21, 2026 and October 18, 2026 respectively.
