SoberMate: BAC tracker

About this app

SoberMate, your night-out copilot.

SoberMate estimates your blood alcohol level in real time and helps you and your friends get home safe. It's not an app that pushes you to drink — it's a prevention and harm-reduction tool.

⚠️ Estimate only. SoberMate is not a breathalyzer, nor a medical or legal device. Never drive after drinking.

REAL-TIME ESTIMATE
• Personalized blood alcohol curve based on your weight, sex, what you've eaten and the time of each drink
• Upcoming peak, time back to zero, suggested time to leave
• A clear chart of your whole night

LIGHTNING-FAST LOGGING
• Add a drink with one tap
• Log water and meals — eating slows absorption, and the app accounts for it
• Home-screen widget: your blood alcohol, live

WITH FRIENDS
• Create a group, join it by scanning a QR code
• See everyone's blood alcohol level in real time
• Pick a designated driver and send a message to the group
• Add a friend even if they don't have the app

SAFETY NET
• Share your location with people you trust
• Help getting home
• Guardian angel: your loved ones know where you are if the night goes wrong

ALSO
• Heat / heatwave alert (heat amplifies the effects of alcohol)
• "Nights that end well" goal with a streak tracker
• Smart notifications, tailored to your plan for the night
• 5 languages: French, English, Spanish, Italian, Chinese
• Works offline; your data stays on your phone
• Free, no ads

Drink less, drink smarter, get home safe. SoberMate helps you enjoy your nights while staying in control.
