Coffee & Sleep

Coffee & Sleep helps you understand how long caffeine stays active in your body – and when sleep becomes realistic again.

Log espresso, filter coffee, cappuccino, latte, energy drinks or black tea (or create your own drinks). The app estimates your current caffeine load using a metabolism model and shows how your intake evolves during the day.

Features:
Quick logging: choose a drink and adjust the time
Sleep ready: prediction when caffeine drops below your sleep threshold
Caffeine curve: view your active caffeine during the day
Daily overview: last coffee, total mg and entries
History: day-by-day overview
Analytics & charts: interactive insights (7/14/30/90 days)
Drink analytics: beverage mix and time patterns
Custom drinks: define caffeine content yourself
Settings: adjust half-life and sleep threshold
Widgets: key values on your home screen

Note:
Coffee & Sleep provides estimates and does not replace medical advice.
