ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
