# 时间书 vs ToDo目标

时间书 and ToDo目标 are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. 时间书 sells 4 one-off in-app purchases and ToDo目标 sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on September 14, 2026 and June 9, 2026 respectively.
