## What is BAC calculator?

Alcocurve shows how alcohol affects your body over time - in a fun, simple way. Just enter your weight, gender, and drinks (with volume, time, and alcohol %), and watch your blood alcohol level rise and fall on a clear, easy-to-read chart. See when you're likely to be sober again, plan your night smarter, and stay in control. It's like having a personal BAC tracker in your pocket!

This app will only estimate the blood alcohol level by using established formulas such as watson and widmark formulas. In order to figure out your true blood alcohol level, you need to measure it using physical instruments, such as a breathalyzer, blood tests or urine tests

### 1/5 — System update

*2025-12-11*

App will not let me select the correct time. Restarted it multiple times. Keeps going to an hour after the time I selected.

**Developer response:** Hello, thank you for the feedback! Could you try again in the newest version to see if you get the same issue?

### 1/5 — bac is way off

*2025-09-25*

Very promising app would be super useful but the Bac says I should be dead after 3 beers with a .5 bac which is laughable

**Developer response:** Hi HPauto2! This app will give the Blood Alchol Concentration in per mille, not percent as you might be used to. Per mille is what is used in many european countries. I have it in the backlog to show it as percent for some countries, such as UK, the US and Australia

### 4/5 — Pretty Good

*2025-09-13*

Nice and easy. Only metric units though

**Developer response:** Thanks for the feedback! Imperial units have now been added :)

### 1/5 — Plain wrong

*2025-09-06*

Said I’d be .77% after 3 regular beers

**Developer response:** Hi dcvxfgvcdtvxsfcdrvfwtcs! As I mentioned in the other comment, this app will give the Blood Alchol Concentration in per mille, not percent as you might be used to. Per mille is what is used in many european countries. I have it in the backlog to show it as percent for some countries, such as UK, the US and Australia
