# 倒数321 vs Countdown

The clearest difference is rating: 倒数321 at 4.6 against Countdown's 3.7. 倒数321 also leads on ads (none vs shown) and ratings volume (34 vs 3). Countdown's advantage is in-app purchases (none vs 17) and update cadence (every 8 days vs monthly). On price, review sentiment and device support there is nothing between them.

Both are free to download. 倒数321 sells 17 in-app purchases, starting at $0.99 per month. Countdown asks for nothing beyond the download.

倒数321 holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: 倒数321 has 34 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of 倒数321'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.

倒数321 ships an update monthly, Countdown every 8 days. The most recent releases landed on September 28, 2026 and October 12, 2026 respectively.
