Caff Conscious: Caffeine Log

Stop guessing when your coffee wears off.

Caff Conscious is a caffeine log and sleep-aware tracker that helps you see how much caffeine is still active, when it may clear, and whether tonight's sleep could be at risk.

Log coffee, tea, soda, energy drinks, and custom drinks in seconds. Start Sipping lets you track a drink over the time you actually drink it, so caffeine absorbs over time instead of all at once.
