Perkly Caffeine Tracker

Your morning coffee is still in your bloodstream at midnight. Perkly shows you exactly how much. THE LIVE CURVE One glance shows the caffeine in your system right now, rising and falling in real time. Scroll back through past days and watch last night's espresso still working this morning. LOG IN ONE TAP Nine everyday drinks - espresso, coffee, latte, cold brew, black tea, green tea, matcha, energy drink, cola - in three sizes. Tap, done. Forgot one? Backdate it. PROTECT YOUR SLEEP Set your bedtime and a caffeine target. Perkly computes your personal last call - the latest moment another coffee still fits - and can nudge you once, right before it passes. No streaks, no guilt, no spam. TUNED TO YOUR BODY Caffeine clearance varies from person to person. Tell Perkly if you smoke, take oral contraceptives, are pregnant, or simply feel caffeine strongly, and the curve adapts to your estimated half-life. EVERYWHERE YOU LOOK Home Screen widgets with the live curve, one-tap quick-log buttons, Lock Screen widgets, and a Live Activity that counts down to sleep-ready. PLAYS WELL WITH OTHERS Every drink is written to Apple Health and counts in Crunchly's food diary automatically.
