# 时间统计 vs 时间书

The clearest difference is update cadence: 时间统计 at every 9 days against 时间书's monthly. 时间统计 also leads on iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 时间统计 sells 3 one-off in-app purchases and 时间书 sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

时间统计 ships an update every 9 days, 时间书 monthly. The most recent releases landed on October 3, 2026 and October 24, 2026 respectively.
