Blood Alcohol Calculator

With Blood Alcohol Calculator you can quickly and easily calculate your blood alcohol content (BAC) by entering a few basic pieces of information. First, create user profiles for you and your friends by entering your name, weight, and gender. Once you've created a user you can add drinks to that user by selecting one of hundreds of built-in drinks or by creating your own custom drinks by adding that awesome cocktail you made at home or that tasty microbrew you just discovered. Lastly, enter how long you've been drinking and calculate the blood alcohol content of you and your friends. This includes a decimal representation of your blood alcohol content (BAC) (Such as 0.08), some possible side effects related to that blood alcohol range, as well as a detailed graph letting you know what your blood alcohol content (BAC) will be over time.

Feel free to comment or email with drink and feature suggestions!

Way off with Irish drinking laws and no way to set base line for different jurisdictions. (At least that I could see) If I had relied on this when drunk I could have ended up in serious trouble.

Thank you for creating an accurate algorithm for us to use simply. Very hard to come by something that gives real insight to nights out.

Relies primarily on mixed / hard drinks. Beers are barely given any attention. With micro brews the rage, more attention to this would be nice. Being able to put volume and abv in custom would be great.

I was so drunk and this program told me I was over the legal limit. Based on the results I did not drive. I think this app might have saved my life. I owe you my life. You are truly the best. Thank you so much!

A good little app to get an Idea of your BAC. I also like the customized drinks you can make. To the one star review and his Martini, the average martini glass servered in a restraunt is like 8oz. You would be consuming around 6 if using the predefined martini in the app.

Very simple little app. Most likely uses basic calculations generalized for the average person. Good for a guess at your BAC and maybe a laugh.

This app is simple, attractive, and very easy to use. It's nice having an estimate of where I'm at with my drinks. Great job!

This is very useful. Works well with large database.

Requires weight entered in something called a "pounds". Wikipedia tells me this is an archaic unit of measurement used only in the US and Liberia.

Once I add a drink, there is no way of deleting it. Even a created profile can't be deleted! Needs a lot of work to be useful.

This app is the cat's pyjamas.
