# Time Arrow vs 柠檬提醒日

The clearest difference is monetization model: 柠檬提醒日 at free against Time Arrow's freemium. 柠檬提醒日 also leads on rating (5.0 vs 4.7). Time Arrow's advantage is ratings volume (88 vs 1) and review sentiment (77% vs 53%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Time Arrow sells 2 in-app purchases, starting at $1.99 per year and 柠檬提醒日 sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

柠檬提醒日 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Time Arrow has 88 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 77% of Time Arrow's written reviews are positive against 53% of 柠檬提醒日's, so the app with the better star average is not the one people write more warmly about.

Time Arrow ships an update every 5 weeks, 柠檬提醒日 every 6 weeks. The most recent releases landed on October 26, 2026 and October 11, 2026 respectively.
