Caffi - Caffeine Coach
Consume Caffeine The Right Way
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Caffi is a caffeine coach disguised as a tracker.
Most caffeine apps just count milligrams. Caffi models how caffeine actually moves through your body, with a 5-hour half-life and a 30-minute absorption ramp, and tells you in plain language when the coffee you're about to drink will ruin your sleep tonight.
LOG EVERY DRINK IN SECONDS
Tap a favorite. Browse 30+ presets. Or log a custom amount. Every entry mirrors to Apple Health's Dietary Caffeine automatically.
SEE YOUR DAY ON A CURVE
Real-time mg in body, peak time, sleep-safe window, and a clean editorial chart that doesn't look like a hospital monitor.
ASK BEAN, YOUR IN-APP COACH
Bean (the friendly drop) is powered by GPT-5 and knows your day's intake, goals, and bedtime. Ask 'when should I stop today?', 'why am I jittery?', or 'how do I cut back without crashing?' and get a real answer in 1 to 3 sentences. No platitudes.
SLEEP IMPACT, EVERY NIGHT
Caffi reads your Apple Health sleep data with permission, correlates it with your caffeine timing, and shows you exactly how much caffeine you'll have in your system at bedtime.
DESIGNED LIKE A MAGAZINE
Dark editorial palette, italic serif headlines, native iOS 26 Liquid Glass chrome. Made to live on your home screen, not get buried in a folder.
PRIVACY FIRST
No ads. Health data stays on device. Your caffeine logs sync to your private Firebase document, scoped to your Apple ID. Read the full policy at caffi.app/privacy.
