# 日子提醒 vs Countdown

The clearest difference is ads: 日子提醒 at none against Countdown's shown. 日子提醒 also leads on update cadence (every 3 days vs every 8 days). Countdown's advantage is iOS requirement (11.0 vs 13.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

日子提醒 ships an update every 3 days, Countdown every 8 days. The most recent releases landed on September 29, 2026 and October 12, 2026 respectively.
