# Master Books vs TT Geometry

The clearest difference is rating: Master Books at 4.9 against TT Geometry's 3.6. Master Books also leads on ratings volume (931 vs 53). TT Geometry's advantage is device support (4 vs 1) and iOS requirement (12.0 vs 18.0). On price, review sentiment, update cadence and ads there is nothing between them.

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

Master Books holds the better App Store score, 4.9 against 3.6. That said, the two scores are not equally well evidenced: Master Books has 931 ratings behind it against 53, so its average is the more settled of the two. Written reviews complicate that: 71% of Master Books's written reviews are positive against 78% of TT Geometry's, so the app with the better star average is not the one people write more warmly about.

Master Books ships an update every 3 months, TT Geometry every 2 months. The most recent releases landed on October 21, 2026 and October 23, 2026 respectively.
