ReceptionRating · Positive reviews · Number of ratings

Hypotenuse holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: Calligraphy Guidelines has 15 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Hypotenuse's written reviews are positive against 60% of Calligraphy Guidelines's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Hypotenuse ships an update every 6 weeks, Calligraphy Guidelines every 3 months. The most recent releases landed on October 3, 2026 and September 27, 2026 respectively.
