# Hypotenuse vs MoNo

The clearest difference is review sentiment: MoNo at 100% against Hypotenuse's 50%. MoNo also leads on ratings volume (6 vs 1) and price ($0.99 vs $2.99). Hypotenuse's advantage is update cadence (every 6 weeks vs every 25 months) and rating (5.0 vs 4.8). On ads, in-app purchases, monetization model and chart position there is nothing between them.

Hypotenuse costs $2.99 and MoNo $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Hypotenuse holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: MoNo has 6 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 100% of MoNo'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, MoNo every 25 months. The most recent releases landed on October 3, 2026 and October 8, 2026 respectively.
