Verdict
The clearest difference is in-app purchases: Daylight Saving Time at none against Atomic Clock PRO's 2. Daylight Saving Time also leads on ads (none vs shown) and rating (5.0 vs 4.7). Atomic Clock PRO's advantage is ratings volume (10K vs 10) and update cadence (every 3 months vs every 19 months). On price, review sentiment and device support there is nothing between them.

Both are free to download. Atomic Clock PRO sells 2 in-app purchases, starting at $1.99 per month. Daylight Saving Time asks for nothing beyond the download.
Daylight Saving Time holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Atomic Clock PRO has 10K ratings behind it against 10, 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 67% of Daylight Saving Time'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, Daylight Saving Time every 19 months. The most recent releases landed on October 11, 2026 and September 26, 2026 respectively.
