# 倒计时日历 vs Countdown

The clearest difference is rating: 倒计时日历 at 4.8 against Countdown's 3.7. 倒计时日历 also leads on ads (none vs shown) and ratings volume (97 vs 3). Countdown's advantage is update cadence (every 8 days vs every 6 months) and review sentiment (55% vs 45%). 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.

倒计时日历 holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: 倒计时日历 has 97 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 45% of 倒计时日历's written reviews are positive against 55% of Countdown's, so the app with the better star average is not the one people write more warmly about.

倒计时日历 ships an update every 6 months, Countdown every 8 days. Both last shipped on October 12, 2026.
