# Protractor+ vs 70 Degree

The clearest difference is rating: Protractor+ at 4.1 against 70 Degree's 2.9. Protractor+ also leads on ads (none vs shown) and ratings volume (10K vs 10). 70 Degree's advantage is in-app purchases (none vs 1) and iOS requirement (12.0 vs 17.6). On price, review sentiment and device support there is nothing between them.

Both are free to download. Protractor+ sells 1 one-off in-app purchase. 70 Degree asks for nothing beyond the download.

Protractor+ holds the better App Store score, 4.1 against 2.9. That said, the two scores are not equally well evidenced: Protractor+ has 10K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 15% of Protractor+'s written reviews are positive against 20% of 70 Degree's, so the app with the better star average is not the one people write more warmly about.

Protractor+ ships an update every 2 months, 70 Degree every 6 months. The most recent releases landed on September 22, 2026 and September 19, 2026 respectively.
