# Digital Angle Finder vs Protractor

The clearest difference is ads: Digital Angle Finder at none against Protractor's shown. Digital Angle Finder also leads on rating (4.1 vs 3.8) and ratings volume (237 vs 16). Protractor's advantage is update cadence (every 9 days vs every 2 months). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Digital Angle Finder holds the better App Store score, 4.1 against 3.8. That said, the two scores are not equally well evidenced: Digital Angle Finder has 237 ratings behind it against 16, 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 60% 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 9 days. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
