# 计数助手 vs 倒数321

The clearest difference is ads: 倒数321 at none against 计数助手's shown. 倒数321 also leads on rating (4.6 vs 4.3) and ratings volume (34 vs 3). 计数助手's advantage is review sentiment (60% vs 50%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. 计数助手 sells 3 in-app purchases, starting at $0.49 per month and 倒数321 sells 17 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

倒数321 holds the better App Store score, 4.6 against 4.3. 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: 60% of 计数助手's written reviews are positive against 50% of 倒数321's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly monthly. Both last shipped on September 10, 2026.
