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.
