# Protractor vs Angle Finder

The clearest difference is rating: Angle Finder at 4.7 against Protractor's 3.9. Angle Finder also leads on ads (none vs shown) and ratings volume (163 vs 14). Protractor's advantage is in-app purchases (none vs 3) and review sentiment (60% vs 33%). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Angle Finder sells 3 in-app purchases, starting at $7.99 per 7 days. Protractor asks for nothing beyond the download.

Angle Finder holds the better App Store score, 4.7 against 3.9. That said, the two scores are not equally well evidenced: Angle Finder has 163 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 60% of Protractor's written reviews are positive against 33% of Angle Finder's, so the app with the better star average is not the one people write more warmly about.

Protractor ships an update every 9 days, Angle Finder every 3 weeks. The most recent releases landed on September 21, 2026 and September 28, 2026 respectively.
