Verdict
The clearest difference is price: Calligraphy Guidelines at Free against Hypotenuse's $2.99. Calligraphy Guidelines also leads on ratings volume (15 vs 1) and review sentiment (60% vs 50%). Hypotenuse's advantage is rating (5.0 vs 3.7) and in-app purchases (none vs 2). On update cadence, ads and device support there is nothing between them.

Calligraphy Guidelines is free to download; Hypotenuse costs $2.99 up front. Calligraphy Guidelines sells 2 in-app purchases, starting at $1.99 per 7 days. Hypotenuse asks for nothing beyond the download.
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.
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.
