DrinkBuddyFrequently asked questions
Short and honest. Still in doubt after reading? Leave the car.
Is DrinkBuddy a breathalyser?
No. DrinkBuddy estimates your BAC from what you enter. Only a breath or blood test measures. In doubt: do not drive.
How accurate is the estimate?
It is a band with a margin, not an exact number. For everything to do with driving we use the upper edge of that margin, so the time to drive again is more likely too late than too early.
May I drive when the battery is green?
Green means that, on the cautious estimate, you are well under your limit. It is not permission and not a guarantee. If you do not feel fit or you are in doubt, do not drive.
Does it work without internet?
Yes. Logging drinks and checking your driving status works offline too. Only sharing a night together needs a connection.
Which limit does the app use?
The legal limit of your country. In the Netherlands that is 0.5 ‰, and 0.2 ‰ for novice drivers. See the limits per country on the How it works page.
Do I need an account?
No, not to track your BAC. For Together you share a night with friends and do need an account.
What does DrinkBuddy do with my data?
Your drinks and profile stay on your phone unless you share a night with others. Read the privacy statement for details.
What does DrinkBuddy cost?
The app is free.
Which phones does it run on?
On Android through Google Play once the app is live, and in the browser as a web app. An iPhone version follows later.
