# 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 monetization model (free vs free with in-app purchases). Dual N's advantage is update cadence (fortnightly vs every 4 months) and iOS requirement (15.0 vs 17.0). On price, rating, ratings volume and ads there is nothing between them.

Both are free to download. Math Workout sells 1 one-off in-app purchase and Dual N sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Dual N holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 130 and 381 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 4 months, Dual N fortnightly. The most recent releases landed on November 13, 2026 and November 14, 2026 respectively.
