Verdict
The clearest difference is rating: Countdown@ at 4.7 against Pendulum's 4.2. Countdown@ also leads on ratings volume (39K vs 16). Pendulum's advantage is ads (none vs shown) and review sentiment (67% vs 37%). On price, update cadence, in-app purchases and monetization model 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. Countdown@ sells 1 one-off in-app purchase and Pendulum sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Countdown@ holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Countdown@ has 39K ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 37% of Countdown@'s written reviews are positive against 67% of Pendulum's, so the app with the better star average is not the one people write more warmly about.
Countdown@ ships an update every 5 days, Pendulum every 9 days. The most recent releases landed on September 24, 2026 and September 10, 2026 respectively.
