## What is Drive Sober?

Drive Sober is a BAC calculator and alcohol tracker that helps you estimate when your blood alcohol concentration may fall below your selected driving limit.

Free to use — no subscriptions or hidden fees. Small ads help support development and keep the app free.

Choose your country, log drinks in seconds, and follow a clear estimated timeline showing how your BAC may rise, peak, and fall over time.

If you're wondering when you may be below the legal BAC limit after drinking — including the next morning — Drive Sober gives you a cautious estimate, not permission to drive.

IMPORTANT

This app provides estimates only and must never be relied upon to decide whether you are legally or medically fit to drive. If you have been drinking, the safest option is not to drive.

If you have been drinking, the safest option is not to drive.
