Verdict

The call

The clearest difference is price: Atomic Clock PRO at Free against Analog Clock's $1.99. Atomic Clock PRO also leads on rating (4.7 vs 4.2) and ratings volume (10K vs 5). Analog Clock's advantage is in-app purchases (none vs 2) and ads (none vs shown). On device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Atomic Clock PRO holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Atomic Clock PRO has 10K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 73% of Atomic Clock PRO's written reviews are positive against 86% of Analog Clock's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Atomic Clock PRO ships an update every 3 months, Analog Clock every 5 weeks. The most recent releases landed on September 23, 2026 and September 6, 2026 respectively.
