cafein: fun coffee tracker

Track caffeine. Protect sleep.

Features & Capabilities

Will tonight's coffee cost you sleep? Cafein projects how much caffeine you'll likely still have in your blood at bedtime, with cortisol science to time your morning.

This app helps you use coffee as fuel and prevent it from costing you sleep. Tap one button to log an espresso, matcha, energy drink, or even a Coca-Cola. A real bi-exponential pharmacokinetics model projects how much caffeine you'll likely still have in your bloodstream when you want to be asleep.

WORK WITH YOUR NATURAL CORTISOL Cafein shows your cortisol awakening response, the natural alertness curve that peaks in the first hour after waking. Drinking coffee inside that window can blunt how strongly caffeine hits. Cafein highlights the window where your first cup tends to land hardest (typically 1.5 to 3.5 hours after wake).

SIMULATE BEFORE YOU SIP Thinking about a 4 pm espresso? Cafein lets you test combinations without committing. See how that hypothetical second coffee changes your bedtime number, then decide.

BUILD YOUR HEALTH STORY Every cup syncs to Apple Health. Your data is yours, exportable as CSV any time, ready to share with your doctor or AI assistant.
