# Time Caps vs 一本日记

The clearest difference is update cadence: 一本日记 at fortnightly against Time Caps's every 6 weeks. 一本日记 also leads on review sentiment (98% vs 84%) and rating (5.0 vs 4.8). Time Caps's advantage is ratings volume (153 vs 18). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Time Caps sells 6 in-app purchases, starting at $3.99 per month and 一本日记 sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

一本日记 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Time Caps has 153 ratings behind it against 18, so its average is the more settled of the two. Written reviews point the same way: 84% of Time Caps's written reviews are positive against 98% of 一本日记's.

Time Caps ships an update every 6 weeks, 一本日记 fortnightly. The most recent releases landed on September 26, 2026 and September 18, 2026 respectively.
