# Nuddle vs Zetamath

Nuddle and Zetamath both sit at 4.9 stars, but that hides the real split: 100% of Zetamath's written reviews are positive against 43% of Nuddle's. Zetamath also leads on in-app purchases (none vs 3). Nuddle's advantage is ads (none vs shown). On price, rating, ratings volume and update cadence there is nothing between them.

Nuddle holds the better App Store score, 4.9 against 4.7. Both are backed by a comparable volume of ratings — 8 and 14 respectively. Written reviews complicate that: 43% of Nuddle's written reviews are positive against 100% of Zetamath's, so the app with the better star average is not the one people write more warmly about.

Nuddle ships an update weekly, Zetamath every 6 days. The most recent releases landed on October 25, 2026 and October 23, 2026 respectively.
