CaffCut: Caffeine Tracker

Had a coffee at 3 PM and lay awake at 2 AM? CaffCut is a caffeine tracker that answers the question before you pour: how much can I still have, and until when?

CUP FIT: ASK BEFORE YOU SIP
Pick a drink and a size. Cup Fit answers three questions at once:
• The most you can have right now and still be under your line at bedtime
• The latest time today a full cup of that drink still fits
• How much caffeine would be left at bedtime if you drank it now
Then log the full cup, or just half, with one tap.

YOUR LAST CUP, ON ONE SCREEN
Today shows one big time: your last full cup for today. Under it you see how much caffeine is in your body now and how much will be left when you go to bed.

THE DECAY RIBBON
A ribbon draws your caffeine fading from now until bedtime. Pick a drink and watch it rise and fall against your bedtime line before you decide.

HOME-SCREEN WIDGET
Add the CaffCut widget to your Android home screen and see your last-cup time at a glance, without opening the app.

LEARNS YOUR OWN HALF-LIFE (Pro)
Caffeine clears faster for some people and slower for others. After a caffeinated day, one tap in the morning (quickly, as usual, took a while) slowly tunes your personal half-life. No wearable needed.

TRENDS
See daily totals and the days you stayed within your line, and share your week as a card. With Pro: weekday patterns and how you fell asleep.

MADE FOR EVERYDAY DRINKS
Espresso, drip, instant, canned coffee, energy drinks, black tea, green tea and cola in small, regular and large sizes. Know your drink's real number? Override it in Settings. ml or fl oz.
