# ZAP短信 vs Countdown Pro

The clearest difference is rating: ZAP短信 at 4.6 against Countdown Pro's 3.6. ZAP短信 also leads on iOS requirement (16.0 vs 18.6). Countdown Pro's advantage is review sentiment (81% vs 50%) and update cadence (every 4 days vs fortnightly). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. ZAP短信 sells 6 in-app purchases, starting at $0.99 per month and Countdown Pro sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ZAP短信 holds the better App Store score, 4.6 against 3.6. Both are backed by a comparable volume of ratings — 10 and 5 respectively. Written reviews complicate that: 50% of ZAP短信's written reviews are positive against 81% of Countdown Pro's, so the app with the better star average is not the one people write more warmly about.

ZAP短信 ships an update fortnightly, Countdown Pro every 4 days. The most recent releases landed on October 12, 2026 and October 17, 2026 respectively.
