# Digital Angle Finder vs Protractor

The clearest difference is rating: Digital Angle Finder at 4.1 against Protractor's 1.8. Digital Angle Finder also leads on in-app purchases (none vs 6) and ratings volume (237 vs 6). On price, review sentiment, update cadence and ads there is nothing between them.

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 24, 2026 respectively.
