# Math Workout vs Dual N

Math Workout and Dual N both sit at 4.4 stars, but that hides the real split: 90% of Math Workout's written reviews are positive against 51% of Dual N's. Math Workout also leads on in-app purchases (none vs 2) and ads (none vs shown). Dual N's advantage is update cadence (fortnightly vs every 2 months). On price, rating, ratings volume and device support there is nothing between them.

Dual N holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 130 and 362 respectively. Written reviews complicate that: 90% of Math Workout's written reviews are positive against 51% of Dual N's, so the app with the better star average is not the one people write more warmly about.

Math Workout ships an update every 2 months, Dual N fortnightly. The most recent releases landed on October 6, 2026 and October 18, 2026 respectively.
