Pitagorín! holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Speed Trigonometry has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 67% of Pitagorín!'s written reviews are positive against 100% of Speed Trigonometry's, so the app with the better star average is not the one people write more warmly about.
Pitagorín! ships an update every 19 months, Speed Trigonometry every 14 months. The most recent releases landed on October 10, 2026 and October 7, 2026 respectively.
