# DueCat vs 時光帳本

The clearest difference is update cadence: 時光帳本 at every 2 days against DueCat's every 5 days. 時光帳本 also leads on iOS requirement (17.0 vs 26.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. DueCat sells 1 one-off in-app purchase and 時光帳本 sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

DueCat ships an update every 5 days, 時光帳本 every 2 days. The most recent releases landed on November 7, 2026 and November 10, 2026 respectively.
