# Angle Meter vs Protractor+

The clearest difference is rating: Protractor+ at 4.1 against Angle Meter's 3.4. Protractor+ also leads on ads (none vs shown) and ratings volume (10K vs 64). Angle Meter's advantage is in-app purchases (none vs 1) and review sentiment (32% vs 15%). On price, update cadence, device support and iOS requirement there is nothing between them.

Both are free to download. Protractor+ sells 1 one-off in-app purchase. Angle Meter asks for nothing beyond the download.

Protractor+ holds the better App Store score, 4.1 against 3.4. That said, the two scores are not equally well evidenced: Protractor+ has 10K ratings behind it against 64, so its average is the more settled of the two. Written reviews complicate that: 32% of Angle Meter's written reviews are positive against 15% 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 2 months. The most recent releases landed on October 2, 2026 and October 6, 2026 respectively.
