Caffff vs Caffeine Tracker

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.

Coffee is fine. Coffee at the wrong hour isn't. Sundown works out the last moment you can still have your usual drink and sleep — then shows you what happens if you have one anyway. AN ANSWER, NOT A NUMBER Every other tracker opens on a total. Sundown opens on a sentence: "Last drip coffee by 2:10 PM." The screen is a sky, and the sun sitting on the curve is the caffeine in you right now. The lower it hangs, the closer the day is to done. SEE IT BEFORE YOU DRINK IT Pick a drink, drag the time, and watch tonight change in front of you. A cold brew at 4pm and a cold brew at 6pm are not the same night, and now you can tell which is which. YOUR BODY, NOT AN AVERAGE People clear caffeine at wildly different speeds — the same cup can wear off in three hours or hang around for ten. Smoking roughly halves it. Hormonal contraceptives roughly double it. Set yours in three taps, or by hand. REAL PHARMACOKINETICS Caffeine peaks about an hour after you drink it, not the instant you log it. Sundown models absorption and elimination properly, including the slow-release kind in pre-workout. EVERYTHING THAT HAS CAFFEINE IN IT Drip, pour over, French press, AeroPress, Moka pot, K-Cup, instant, cold brew, nitro, espresso drinks. Black, green, white and oolong tea, matcha, yerba mate, chai. Energy drinks and soda. Plus the caffeine in dark chocolate, in painkillers, and in caffeine pills and gum. Make your own for anything missing. COME DOWN WITHOUT THE HEADACHE Cutting caffeine fast is what causes the headache. Taper plans step you down week by week and never take more than a quarter at a time. ON YOUR PHONE, NOT OURS No account. No sign-in. Your log never leaves the device. Apple Health sync works in both directions. Widgets on the Home and Lock Screen, a reminder 20 minutes before your cutoff, and one-tap logging from Siri and Shortcuts. — Sundown Pro Try everything free for 3 days.
