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.
