# The Clocks vs Atomic Clock PRO

The clearest difference is update cadence: The Clocks at every 2 weeks against Atomic Clock PRO's every 3 months. The Clocks also leads on iOS requirement (12.0 vs 15.6). Atomic Clock PRO's advantage is rating (4.7 vs 4.5). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. The Clocks sells 1 one-off in-app purchase and Atomic Clock PRO sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Atomic Clock PRO holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 21K and 10K respectively. Written reviews complicate that: 79% of The Clocks's written reviews are positive against 73% of Atomic Clock PRO's, so the app with the better star average is not the one people write more warmly about.

The Clocks ships an update every 2 weeks, Atomic Clock PRO every 3 months. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
