# Caffeine Tracker vs Decaf AI

The clearest difference is update cadence: Caffeine Tracker at every 5 days against Decaf AI's every 6 weeks. Caffeine Tracker also leads on ratings volume (40 vs 8). Decaf AI's advantage is review sentiment (100% vs 83%) and iOS requirement (13.4 vs 26.0). 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 Decaf AI sells 4 in-app purchases, starting at $9.99 per 7 days. 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 Decaf AI. That said, the two scores are not equally well evidenced: Caffeine Tracker has 40 ratings behind it against 8, 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 Decaf AI's.

Caffeine Tracker ships an update every 5 days, Decaf AI every 6 weeks. The most recent releases landed on October 17, 2026 and October 15, 2026 respectively.
