# AdaptedMind Math vs Shelfy Books

The clearest difference is rating: AdaptedMind Math at 4.7 against Shelfy Books's 4.0. AdaptedMind Math also leads on update cadence (every 4 days vs every 5 months) and ratings volume (13K vs 1). Shelfy Books's advantage is review sentiment (100% vs 60%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. AdaptedMind Math sells 3 in-app purchases, starting at $9.95 per month and Shelfy Books sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

AdaptedMind Math holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: AdaptedMind Math has 13K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 60% of AdaptedMind Math's written reviews are positive against 100% of Shelfy Books's, so the app with the better star average is not the one people write more warmly about.

AdaptedMind Math ships an update every 4 days, Shelfy Books every 5 months. The most recent releases landed on November 11, 2026 and November 5, 2026 respectively.
