# Math Rings vs 3o

The clearest difference is review sentiment: Math Rings at 100% against 3o's 50%. 3o's advantage is rating (4.8 vs 4.2) and update cadence (every 6 weeks vs every 20 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

3o holds the better App Store score, 4.8 against 4.2. Both are backed by a comparable volume of ratings — 5 and 4 respectively. Written reviews complicate that: 100% of Math Rings's written reviews are positive against 50% of 3o's, so the app with the better star average is not the one people write more warmly about.

Math Rings ships an update every 20 months, 3o every 6 weeks. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
