Verdict
The clearest difference is ads: Countdown Timer at none against AClock's shown. Countdown Timer also leads on rating (4.8 vs 4.5) and ratings volume (1.2K vs 53). AClock's advantage is update cadence (every 2 months vs every 7 months). On price, review sentiment, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Countdown Timer holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Countdown Timer has 1.2K ratings behind it against 53, so its average is the more settled of the two. Written reviews complicate that: 85% of Countdown Timer's written reviews are positive against 89% of AClock's, so the app with the better star average is not the one people write more warmly about.
Countdown Timer ships an update every 7 months, AClock every 2 months. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
