CaffeineMate: Caffeine Tracker
Coffee Tracker & Sleep Cutoff
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Know your Last Call: the latest time for coffee that still lets you sleep. A caffeine curve tuned to your body, a sleep forecast, and one reminder at the right moment.
Love coffee and still want to sleep? CaffeineMate tells you when to stop.
Caffeine leaves everyone at a different speed. CaffeineMate estimates your personal caffeine half-life from your weight, age and sensitivity, then turns every drink you log into one live curve: what is in your system now, when it peaks, and how much will be left at bedtime.
YOUR LAST CALL
Set your bedtime and CaffeineMate works out your Last Call: the latest time for caffeine that still clears before you sleep. Have that afternoon cold brew or skip it, knowing what it means for tonight.
SEE CAFFEINE LEAVE YOUR BODY
A real-time metabolism curve shows your current level in mg, your peaks and the moment you drop below the level that is friendly to sleep.
FORECAST TONIGHT'S SLEEP
Connect Apple Health and CaffeineMate compares your caffeine with your sleep. Over time you see how your coffee habits relate to your nights, and get a forecast for tonight.
