ReceptionRating · Positive reviews · Number of ratings

Math Duel holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: Math Duel has 235 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 64% of Math Duel's written reviews are positive against 75% of DIY Human Body's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Math Duel ships an update every 6 weeks, DIY Human Body every 2 months. The most recent releases landed on October 29, 2026 and November 1, 2026 respectively.
