## What is Caffff?

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.
