Last Cup: Caffeine & Sleep

About

Last Cup helps you know when to stop drinking coffee so it does not steal your sleep. Coffee is great. Bad timing is not. Most caffeine trackers only count milligrams. Last Cup goes further: it estimates how much caffeine is still active in your body and shows how it may affect tonight’s sleep. LOG CAFFEINE IN SECONDS Track coffee, espresso, cappuccino, latte, tea, matcha, soda, or energy drinks in just a few taps. SEE WHAT IS STILL ACTIVE A live caffeine ring shows your estimated active caffeine level in real time, so you can understand what is still in your system before bedtime. KNOW YOUR COFFEE CUTOFF Before you drink, Last Cup estimates the potential sleep impact: - extra time to fall asleep - caffeine remaining at bedtime - possible sleep quality impact - simple sleep score - best time for your last cup PERSONALIZED TO YOU Caffeine does not affect everyone the same way.
