A BAC calculator & drink tracker for Android — real-time blood alcohol content, right in your pocket.
- 6 countries supported
- 5,800+ drinks database
- No account needed
Built for accuracy. Designed for safety.
A BAC calculator for Android built on your body composition, not your weight alone — with the legal limits of your country.
The Right Science for Your Body
a Jackson (2002) body-fat estimate with Norberg distribution volume for Western populations, a dedicated South Asian model for Indian body composition, the US Navy tape-measure method in Premium, and an elimination rate set by your sex and age (Jones 2010) — not one generic formula for everyone.
One-Tap Safe Ride
When your BAC is above zero, a ride home appears automatically — the rideshare or taxi apps used in your country, one tap away. No fumbling through apps after a few drinks.
5,800+ Drinks Database
Beer, wine, cocktails, spirits, ciders, seltzers and more. Browse by category, search by name, or quick-add your usual. Precise ABV and serving sizes.
Your Drinking Data Stays on Your Phone
No account to create. Your drink log, BAC history and body details are stored only on your phone — we never receive them. Usage statistics and crash reports can be switched off in Settings.
