Sober Drive: When Can I Drive
An estimate, not a licence
Log a drink in seconds and get a Widmark-formula estimate of your current blood alcohol level, the minutes until you are back under the legal limit and the countdown until you are fully sober.
Act IWhat it does
Log a drink in seconds
Set your sex and weight once, then tap the drink type and when you finished it.
Live BAC estimate
The home screen shows an estimate that decays in real time as the hours pass.
Two countdowns
Minutes until you are under the limit, and minutes until 0.00.
Adjustable limit
Track against 0.08 or switch to 0.05 where that is the legal limit.
Add drinks as you go
Keep the log honest through the evening.
No account
Your log stays on the device. The free version shows ads; a one-time purchase removes them.
Act IIWho it is for
Sober Drive is an estimate, not a measurement. It does not replace a breathalyser or a blood test, and it is not legal advice. Alcohol affects every body differently. If you are in any doubt, do not drive.
