# 生日提醒 vs Time Arrow

The clearest difference is update cadence: 生日提醒 at every 11 days against Time Arrow's every 5 weeks. 生日提醒 also leads on rating (4.9 vs 4.7). Time Arrow's advantage is review sentiment (77% vs 67%) and iOS requirement (9.0 vs 11.0). On price, ratings volume, ads and in-app purchases there is nothing between them.

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

生日提醒 holds the better App Store score, 4.9 against 4.7. Both are backed by a comparable volume of ratings — 192 and 88 respectively. Written reviews complicate that: 67% of 生日提醒's written reviews are positive against 77% of Time Arrow's, so the app with the better star average is not the one people write more warmly about.

生日提醒 ships an update every 11 days, Time Arrow every 5 weeks. The most recent releases landed on October 21, 2026 and October 18, 2026 respectively.
