Breathalyser – BAC Tracker

Breathalyser is a modern BAC calculator using Erik Widmark’s formula combined with a real-time alcohol metabolism engine. The new 2.0 update introduces the Drink Revolver – a fast and intuitive way to log consumed beverages with just one tap.

The application now features a live BAC chart that shows how your blood alcohol concentration changes over time. You can track the peak level, estimated metabolic elimination, and the exact time when you will reach 0‰.

Main features

• Drink Revolver 2.0 – select drinks instantly
• Live BAC chart with dynamic colour scale
• Metabolism tracking using statistical coefficients
• Automatic calculation of peak BAC and sober-up time
• Customisable drink presets (volume, %ABV, containers)
• Gender and body-weight adjustments
• Realistic absorption and elimination rates
• Modern, simple and intuitive interface

How it works

The application uses the Widmark formula together with absorption and elimination models based on scientific research. The results are indicative and may differ from your actual BAC, depending on physiology, health, and many individual factors.

Important

This app is not a professional breathalyser. Do not drive or operate machinery after drinking alcohol. Always follow your local legal regulations.
