BAC calculator - calculate after what time the body will be sober.

Features & Capabilities

The Breathalyser BAC Calculator Chrome extension lets you estimate how long it will take for your body to reach sobriety after drinking alcohol. Using the modified Erik Widmark algorithm, it calculates blood alcohol levels considering factors like gender, body weight, height, alcohol consumed, duration, and stomach saturation. This tool offers alcohol management and personalized data input for accurate results. While it provides a helpful guide, note that individual metabolism varies and a real breathalyser is recommended for 100% certainty.

The extension’s user-friendly interface helps manage consumption details and provides timely sobriety estimations, making it ideal for responsible alcohol use. The intuitive design incorporates visuals by Freepik and others for a seamless user experience.

User Reviews

Users appreciate the app for its unique feature that allows inputting the exact time drinks were consumed, extensive drink database, and generally accurate BAC estimations comparable to real breathalyzers. It is praised for its usefulness in deciding sobriety and safe driving. However, several users report that the after-consumption calculator often throws errors, recent updates have reduced accuracy, and some input errors appear even when data is correct.

Pros

Allows entering the time when the drink was consumed, not just live time.
App provides useful and accurate estimations of BAC matching real breathalyzer results.
Includes an extensive collection of alcoholic drinks with their alcohol percentage, making data entry easy.
User-friendly interface, intuitive, and helpful for drinkers to track alcohol intake and sobriety timing.
Useful tool to check if you are sober enough to drive, has legal alcohol limits for many countries.

Cons

The after consumption calculator often produces an error after entering alcohol and pressing next.
Estimations became drastically inaccurate after recent updates, with discrepancies between during and after drinking times.
App sometimes shows confusing errors like "start time must be after end time" even with correct input.

Recent reviews

Only app I've seen where you can enter time drink was consumed. Every other app I see is only live time.

Old: Most of the time the app works properly. The after consumption calculator does not work properly. It will give an "error" after entering alcohol & pressing next. I have re-installed & still doesn't work. New: Since the recent update the estimations have become drastically inaccurate. The app worked better before. The during drinking & after drinking should be similar, not hours of difference. To input a shot, it doesn't allow a decimal number like 1.5 oz. Shot. Check duration of sobriety
