Last Cup: Caffeine & Sleep

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. Last Cup adapts to your profile, sleep rhythm, caffeine sensitivity, and daily habits to give you a more personal caffeine cutoff.

BUILT FOR BETTER SLEEP HABITS

Use Last Cup to:
- avoid coffee too late in the day

SCIENCE-INFORMED
