# Book Context vs 读书迹

The clearest difference is update cadence: 读书迹 at every 5 days against Book Context's every 3 weeks. 读书迹 also leads on device support (3 vs 1) and iOS requirement (15.1 vs 18.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Book Context sells 2 in-app purchases, starting at $0.99 per month and 读书迹 sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Book Context ships an update every 3 weeks, 读书迹 every 5 days. Both last shipped on October 24, 2026.
