DrinkKeeper

DrinkKeeper helps you keep track of a night out — what everyone drank, what it costs, and roughly where your blood alcohol level sits.

Add the people you are out with, log each round, and the app keeps the running total for the whole group. At the end of the night you get a clear
receipt showing who had what and what they owe.

WHAT YOU CAN DO

• Keep shared lists per occasion, with a name and location, so last week's night out stays separate from tonight's
• Log drinks per person and see the group total build up as the evening goes
• Get a BAC estimate based on your weight, height, sex, age and the timing of your drinks, using the Widmark formula with a two-phase absorption model
• See an estimate of when you are likely to be sober again
• Generate a receipt for the group and share it through any app on your phone
• Follow calories from drinks and snacks
• Start from 46 preloaded drinks and snacks across six categories — beers, wines, cocktails, soft drinks, snacks and other — or add your own with their own volume, percentage, price and calories
• Give everyone a profile picture so lists stay readable at a glance

PRIVATE BY DESIGN

Everything you enter stays on your phone, in a local database. DrinkKeeper has no accounts, no sign-up and no analytics — the app does not even request internet access. Nothing is uploaded, because there is nowhere to upload it to.

AVAILABLE IN

English, Dutch, German, French, Spanish, Italian and Portuguese.

IMPORTANT

DrinkKeeper is for people of legal drinking age and is meant for awareness and for settling the bill, not for deciding whether you can drive.

The BAC figure is an estimate from a simplified formula. Real blood alcohol depends on food, medication, health, fatigue and individual metabolism, and can be considerably higher than any calculation suggests. Never use this app to judge whether it is safe to drive or operate machinery. If you have been drinking, do not drive.
