About
Most coffee apps count cups. Caffeinity tells you what's actually in you.
Every brew you log decays on a real half-life curve, so the number on your home
screen is what's in your bloodstream this minute — not a total that resets at
midnight and tells you nothing.
Tell it when you go to bed and it works backwards: the latest you can have one
more and still sleep fine. No guessing at four in the afternoon.
Logging takes a tap. Your usual brews sit at the top of the sheet, ready to go.
Dial in a new one when you feel like it — dose, water, ratio, decaf — or don't
think about it at all.
It keeps your shelf too. Grams left in each bag, days off roast, cups remaining,
what a cup actually costs you. Bags draw down on their own as you brew.
Over time you get the shape of your habit: milligrams a day, when your first cup
lands, days you went over. And the occasional observation you'd never catch
yourself — like which day of the week quietly runs hottest.
No streaks. No badges. Nothing asking you to come back. Caffeinity is a
well-set page you glance at, then put away.
Pro unlocks your full history, weekly observations, cost per cup, an unlimited
shelf, and your personal cut-off time.
Works offline. Your log is yours.
