# ClockN vs Atomic Clock

The clearest difference is review sentiment: Atomic Clock at 100% against ClockN's 50%. Atomic Clock also leads on update cadence (every 6 weeks vs every 4 months) and ratings volume (5 vs 1). ClockN's advantage is rating (5.0 vs 4.8) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. ClockN sells 3 in-app purchases, starting at $19.99 per month and Atomic Clock sells 2 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

ClockN holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Atomic Clock has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of ClockN's written reviews are positive against 100% of Atomic Clock's, so the app with the better star average is not the one people write more warmly about.

ClockN ships an update every 4 months, Atomic Clock every 6 weeks. The most recent releases landed on October 11, 2026 and October 23, 2026 respectively.
