Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
