## What is CaffOut?

The cup is empty. The caffeine isn’t.

CaffOut is a local-first caffeine tracker and coffee journal. It brings drink logging, transparent half-life estimates, reactive characters, and photo Stamps together so the possible after-effects of your last cup are easier to understand and remember.

• Log coffee, tea, energy drinks, and custom drinks quickly
• Estimate possible remaining caffeine for each recorded drink
• Save an unknown drink first and complete its caffeine value later
• Remember the day with characters, a calendar, photo Stamps, and optional places
• Keep drink records, preferences, and custom Stamps in local app storage by default
• Unlock unlimited custom Stamps with one optional lifetime purchase—no subscription

CaffOut shows the formula, inputs, and limitations behind its reference estimates. It does not measure your body in real time, provide medical advice, or guarantee sleep outcomes.

Download CaffOut to log each cup and see how long its effects may linger.
