# Caffeine Tracker vs Caffeine Clock

The clearest difference is monetization model: Caffeine Clock at free against Caffeine Tracker's freemium. Caffeine Clock also leads on iOS requirement (16.4 vs 26.0). On price, rating, review sentiment and ratings volume there is nothing between them.

Both are free to download. Caffeine Tracker sells 4 in-app purchases, starting at $1.99 per month and Caffeine Clock sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Caffeine Tracker holds the better App Store score, 4.9 against 4.7. Both are backed by a comparable volume of ratings — 40 and 28 respectively. Written reviews complicate that: 79% of Caffeine Tracker's written reviews are positive against 80% of Caffeine Clock's, so the app with the better star average is not the one people write more warmly about.

Caffeine Tracker ships an update every 5 days, Caffeine Clock weekly. Both last shipped on October 24, 2026.
