# Measure Angles vs Protractor Smart

The clearest difference is ads: Protractor Smart at none against Measure Angles's shown. Protractor Smart also leads on rating (4.6 vs 4.2) and iOS requirement (14.0 vs 16.6). Measure Angles's advantage is update cadence (fortnightly vs every 21 months) and ratings volume (2K vs 242). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Measure Angles sells 8 in-app purchases, starting at $4.99 per 7 days and Protractor Smart sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Protractor Smart holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Measure Angles has 2K ratings behind it against 242, so its average is the more settled of the two. Written reviews complicate that: 47% of Measure Angles's written reviews are positive against 40% of Protractor Smart's, so the app with the better star average is not the one people write more warmly about.

Measure Angles ships an update fortnightly, Protractor Smart every 21 months. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
