# Atomic Clock PRO vs WristTrack

The clearest difference is ratings volume: Atomic Clock PRO at 10K against WristTrack's 171. WristTrack's advantage is update cadence (monthly vs every 3 months) and review sentiment (90% vs 73%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Atomic Clock PRO sells 2 in-app purchases, starting at $1.99 per month and WristTrack sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

WristTrack holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Atomic Clock PRO has 10K ratings behind it against 171, so its average is the more settled of the two.
