# Atomic Clock PRO vs Analog Clock

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.

Atomic Clock PRO is free to download; Analog Clock costs $1.99 up front. Atomic Clock PRO sells 2 in-app purchases, starting at $1.99 per month. Analog Clock asks for nothing beyond the download.

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.

Atomic Clock PRO ships an update every 3 months, Analog Clock every 5 weeks. The most recent releases landed on September 25, 2026 and September 6, 2026 respectively.
