Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Track caffeine with a metabolism curve built for YOUR body. Live Activities, Apple Watch, 100+ drinks. Free to use, no subscription ever.
Tazza is the caffeine tracker that actually knows you.
Unlike generic trackers that treat everyone the same, Tazza builds a real-time caffeine decay curve personalized to your unique metabolism, factoring in sensitivity, health conditions, medications, and lifestyle. Watch your caffeine level drop in real-time and know exactly when you're sleep-ready.
REAL-TIME CAFFEINE CURVE
See your actual caffeine level right now — not a guess, but a pharmacokinetic model personalized to you. Watch the curve update live with every drink you log.
SLEEP-SAFE COUNTDOWN
"You'll be sleep-ready by 9:47 PM." No more guessing whether that afternoon coffee will keep you up tonight.
PERSONALIZED METABOLISM
Your body isn't average. Tazza adjusts for pregnancy, smoking, contraceptive use, CYP1A2 medications, and your personal sensitivity level. Your curve. Your body.
APPLE WATCH
Log drinks from your wrist in one tap. Complications show your current caffeine level at a glance. Smart predictions suggest what you'll drink based on time of day and habits.
LIVE ACTIVITIES & DYNAMIC ISLAND
Your caffeine status lives on your Lock Screen and Dynamic Island — always visible, always current. No other caffeine tracker has this.
WIDGETS EVERYWHERE
8 widget types for Home Screen and Lock Screen. Plus a Control Center button for instant logging.
100+ DRINKS BUILT IN
Starbucks, Dunkin', Dutch Bros, Peet's, Tim Hortons, Monster, Celsius, Red Bull, and more. Plus create unlimited custom drinks.
SMART NOTIFICATIONS
Get reminded before your personal caffeine cutoff, warned when approaching your daily limit, and celebrated for tracking streaks.
INSIGHTS THAT MATTER (Premium)
Full analytics with weekly trends, streaks, and activity heatmaps. Sleep correlation insights show how caffeine affects your rest. Siri Shortcuts let you log hands-free.
Free to use with a generous feature set. No subscriptions, Premium is a one-time $6.99 purchase.
Ratings & Reviews
Apple Health sync is now more reliable. Editing, deleting, or undoing a caffeine entry keeps your Health data accurate without creating duplicate or outdated samples.
You can also clean up older mismatched Health data from Settings.
We’ve improved Health permission guidance, refreshed connection status automatically, and polished the caffeine chart.
