Unbuzz: Caffeine Tracker

Before your next coffee, check if it still fits your bedtime.

Unbuzz is a caffeine tracker for coffee, tea, energy drinks and more. Log what you drink, and before the next one, ask "Can I have another?": Unbuzz estimates how that drink would add up by your bedtime and answers right away.

CAN I HAVE ANOTHER?
Pick a drink and see whether it still fits your bedtime estimate, before you log anything. Your last drink is filled in, so the answer takes one tap.

FIND YOUR DRINK FAST
Search a catalogue of branded coffee shop drinks, energy drinks, sodas and teas, with each size listed separately. Your recent drinks come first, even when you search. Scan a barcode or create your own drink when you need to.

A FREE WIDGET
Add the free "Can I have another?" widget to your Home Screen or Lock Screen and see the answer at a glance.

SEE YOUR CAFFEINE TIMELINE
Follow an estimate of your caffeine level through the day, with your bedtime level and today's drinks.

LEARN IT IN A MINUTE
Short how-to videos show each part of the app, with captions in your language.

PRIVATE BY DESIGN
The calculations run on your device. No account is needed. Analytics are optional and off until you agree.

Some features require an in-app purchase or subscription. Check the app for available plans.

Caffeine levels and timing are estimates. Individual responses vary. Unbuzz does not measure caffeine in your body, predict when you will fall asleep, or provide medical advice.
