Caffeine Tracker & Sleep Clock

See exactly how much caffeine is still in your body — live decay curve, daily limit, sleep impact and cutoff reminders in one simple tracker.

Stop guessing how much caffeine is really in your system. Log every coffee, tea, or energy drink and watch a live decay curve show exactly when you'll be caffeine-free.

TRACK EVERY SOURCE • Log coffee, espresso, tea, energy drinks, soda, decaf, or your own custom drink • Auto-estimated mg per drink type, with manual override and cup size adjustment • See your running daily total against a limit you set

SEE YOUR CAFFEINE CURVE • A live half-life decay chart shows how much caffeine remains in your body right now and through the day • Built on real pharmacokinetics — caffeine's roughly 5-hour half-life

PROTECT YOUR SLEEP • Tag how you slept each night and spot the connection between afternoon caffeine and rough nights • Set a personal cutoff time and get a reminder before it's too late for that last coffee

ASK BARISTA • Chat with Barista, your in-app AI coffee expert, for quick answers on brewing, drink recommendations and caffeine tolerance

Simple logging, a clear picture of your caffeine load, and better sleep — all in one focused app.
