Verdict
The clearest difference is rating: Grade 12 at 4.8 against OneBookStore's 4.0. Grade 12 also leads on in-app purchases (none vs 10) and ratings volume (5 vs 1). OneBookStore's advantage is update cadence (every 2 months vs every 9 months). On price, ads and device support there is nothing between them.

Both are free to download. OneBookStore sells 10 one-off in-app purchases. Grade 12 asks for nothing beyond the download.
Grade 12 holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Grade 12 has 5 ratings behind it against 1, so its average is the more settled of the two.
OneBookStore ships an update every 2 months, Grade 12 every 9 months. The most recent releases landed on September 24, 2026 and October 24, 2026 respectively.
