Log a coffee and watch it move on a live decay curve. Caffff shows the caffeine in your body right now and warns you before it steals tonight's sleep. Caffff tracks the caffeine in your body over time and helps you protect your sleep. Log a drink and watch a live curve of the caffeine in your bloodstream — see how much is in you right now, what you'll have left at bedtime, and the exact "last call" time to stop drinking and still sleep clean. • Live decay curve. A single-compartment pharmacokinetic model with a configurable half-life, drawn beautifully in dark mode. • One-tap logging. Quick-add tiles for coffee, espresso, energy drinks and more — the strip learns your habits. Backdate a drink you forgot in two taps. • Sleep protection. Set your bedtime and a sleep-safe threshold; Caffff warns you when a drink puts tonight at risk and reminds you of your daily caffeine cutoff. • Home Screen & Lock Screen widgets. Your level at a glance, with one-tap logging. • Weekly insights. Your total, daily average, top drink, and week-over-week trend. Caffff Pro adds full history, Health sleep insights, a custom half-life, and unlimited custom drinks. Caffff shows estimates, not measurements, and is not medical advice. Health: Caffff can read your sleep (Pro) and optionally write your caffeine to Health. This data stays on your device. Caffff has no servers, no analytics, and no tracking.
