Caffeinity

About this app

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. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://caffeinity-web-git-691393524886.us-central1.run.app/privacy.html

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
