# Angle Meter vs Protractor

The clearest difference is rating: Angle Meter at 3.4 against Protractor's 1.8. Angle Meter also leads on in-app purchases (none vs 6) and ratings volume (64 vs 6). Protractor's advantage is ads (none vs shown) and review sentiment (64% vs 32%). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Protractor sells 6 in-app purchases, starting at $4.99 per month. Angle Meter asks for nothing beyond the download.

Angle Meter holds the better App Store score, 3.4 against 1.8. That said, the two scores are not equally well evidenced: Angle Meter has 64 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 32% of Angle Meter'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.

Angle Meter ships an update every 4 months, Protractor every 5 weeks. The most recent releases landed on October 15, 2026 and October 2, 2026 respectively.
