# Super Clock vs Atomic Clock PRO

The clearest difference is rating: Atomic Clock PRO at 4.7 against Super Clock's 3.7. Atomic Clock PRO also leads on ratings volume (10K vs 34). Super Clock's advantage is update cadence (fortnightly vs every 3 months) and iOS requirement (12 vs 15.6). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Super Clock sells 2 one-off in-app purchases 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 3.7. That said, the two scores are not equally well evidenced: Atomic Clock PRO has 10K ratings behind it against 34, so its average is the more settled of the two. Written reviews point the same way: 71% of Super Clock's written reviews are positive against 73% of Atomic Clock PRO's.

Super Clock ships an update fortnightly, Atomic Clock PRO every 3 months. Both last shipped on September 23, 2026.
