# 吾身 vs 时间书

The clearest difference is iOS requirement: 吾身 at 11.0 against 时间书's 15.0. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 吾身 sells 1 one-off in-app purchase and 时间书 sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

吾身 ships an update every 6 weeks, 时间书 monthly. The most recent releases landed on October 20, 2026 and October 24, 2026 respectively.
