# Caffeine Tracker vs Clarity

Caffeine Tracker and Clarity both sit at 4.9 stars, but that hides the real split: 100% of Clarity's written reviews are positive against 83% of Caffeine Tracker's. Clarity also leads on iOS requirement (18.0 vs 26.0). Caffeine Tracker's advantage is ratings volume (40 vs 2) and update cadence (every 5 days vs every 2 weeks). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Caffeine Tracker sells 4 in-app purchases, starting at $1.99 per month and Clarity sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Caffeine Tracker against 5.0 for Clarity. That said, the two scores are not equally well evidenced: Caffeine Tracker has 40 ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 83% of Caffeine Tracker's written reviews are positive against 100% of Clarity's.

Caffeine Tracker ships an update every 5 days, Clarity every 2 weeks. The most recent releases landed on October 17, 2026 and October 16, 2026 respectively.
