Alcool Test is not a certified breathalyzer: it's an indicative, informational estimate only. It can never be used to determine fitness to drive. Learn more.
Real-time estimate
100% private, no sign-up
The only safe BAC for driving is 0.00. Alcool Test is an information and prevention tool, not a measuring instrument. If in doubt, never drive: call a friend, a taxi, or take public transport. More on our safety page.
Features
Built for the night out, never for driving.

100% private, no sign-up
No account needed: your body profile, weight and drink history stay exclusively on your phone, never on a server.
Stats & BAC curve
Visualize your estimated BAC curve and a statistics dashboard over 7, 30 or 90 days, computed entirely on your device.
Personalized tips
Actionable advice throughout the night — drink water, eat something — never to encourage more consumption.
Free to start
The core app is free, supported by discreet ads. An optional VIP 👑 subscription removes ads and unlocks the statistics dashboard, the BAC curve and the home screen widget.
Frequently asked questions
Before you download
Does it replace a breathalyzer?
No. Alcool Test computes a theoretical estimate from information you enter (weight, sex, drinks, timing). It doesn't measure anything physically and can never be used to decide whether you're fit to drive. Only a certified breathalyzer gives a reliable reading.
Is my data private?
Yes. All your data (body profile, drinks, history, statistics) stays only on your phone: no account is required and nothing is sent to a server. Details in our privacy policy.
What's the minimum age to use it?
Alcool Test is reserved for adults (18 and older, or the legal drinking age in your country). Age confirmation is required at setup.
Is the app free?
Yes, the core app is free and ad-supported. An optional VIP subscription unlocks advanced features; its terms and pricing are always shown in-app before purchase.
Which platforms is it available on?
Android, on Google Play.
