IntelliDrink PRO - Blood Alcohol Content (BAC) Calculator

By Raphael Wichmann

Open iTunes to buy and download apps.


IntelliDrink is a sophisticated blood alcohol content (BAC) calculator. It has a simple user interface and uses a complex algorithm for precise calculations.

Watch your BAC rise and fall on the graph and analyze your consumption. Set a limit and get notified when you exceed or fall below your limit.

Dr. Gary Rosen, Professor of Mathematics, University of Southern California (USC):
"We used IntelliDrink to obtain estimated BAC in a research project aiming to calibrate sophisticated data analysis software for autonomous transdermal alcohol sensors. It has been ideal for our purposes, and we are planning on using it in a number of future studies."

User comments:

"As an expert in the field of BAC absorption and elimination, I am impressed by this app."

"Incredible. Absolutely wonderful and fascinating algorithm that takes into account absorption time."

"By far the best drink tracking app I've found... Cheers!"

"Way better (and easier to use) than expected. I can really, truly see this being a life-saver (or DUI)."

"Great app. I have been using it for a few weeks and tonight used it side by side with an Alco-sensor device that was just calibrated. It was within .001! I was surprised. This thing is accurate. Good job."

"Fully customizable in letting u add, edit, and save any number of drinks to ur list, specifying default sizes, percent alcohol/strength, and typical drink duration, this app is simply amazing. Great that it factors in sex, age, and weight as well. None of the other bac/drink tracking apps out there even come close!"

"A great deal. Seems very accurate. It really helps you get an idea of how long after a drink it affects you. The app looks great. The multi users is easy to switch between, letting you easily track friends. They seem to have the formula that is most accurate. Takes into account the time it takes you to have a drink. Real time graph is informative. 10 star A+++ app"

Here are some features of IntelliDrink:

- It uses a sophisticated algorithm for precise calculations based on scientific knowledge.

- It calculates the absorption and metabolism of alcohol over time.

- You can analyze your alcohol consumption using the statistics it provides.

- You own your data! IntelliDrink does not send any private data to the cloud.

- It features a BAC alarm that notifies you when you exceed or fall below your limit.

- It considers your age, weight, height, gender, drinking frequency and stomach content.

- You can create new drinks or modify existing ones.

- It includes your drink history, which gives you an overview of the drinks you’ve had.

- It’s battery friendly, with no background calculations.

A lot of effort was put into IntelliDrink’s algorithm for calculating the values. Most BAC calculators assume that you quickly downed your drink, and, even worse, they assume that you’ve already completely digested the drink. This is not how it works in real life.

The core concept of IntelliDrink is based on the scientifically accepted Widmark formula, which is used by the German justice system. This formula allows you to your BAC based on how many grams of alcohol you ingested.
But this formula does not consider the amount of time it takes you to ingest a drink, the content level of your stomach, or the speed of your metabolism.

IntelliDrink takes all of these factors into consideration because it uses a much more precise algorithm. When you use IntelliDrink, you can access data supported by solid scientific research in a beautiful and easy-to-use interface.

Please note that the values should be used only as a guide and should never be used to determine if you are able to drive.

Although IntelliDrink offers a high level of precision, the values shown are influenced by many factors. IntelliDrink therefore accepts no responsibility or liability for the accuracy or completeness of the information provided.

Get this App

I like this App! At the very least it has me looking into what I'm drinking and the effect drinking is having in my body and mind. Is it 100% accurate? Well, the app does not make that claim, and how you know unless you get a breathalyzer or blood test as you go and compare? I ain't no lab rat, I won't be doing that. Instead, I'll drink, enter the info, and compare what I feel to what science folks say at certain BACs. Already this app has changed me habits; I realized I was drinking way too much, needlessly, and I don't need to pound em down to have a good time. I also realized that one beer isn't going to make me unsafe to drive. Based on the app, I can have 3-4 drinks and still be under the legal limit (tho why risk it?). That takes away any anxiety I had towards drinking and makes it seem fun again. Stupid high school kids might want to try using this app and consider holding back on excessive drinking until they need to gain admittance to their father's vaunted fraternity. This app would admirably serve whatever role, necessary. Just use it. It'll help start a conversation towards more responsible drinking, at the very least.

The only thing missing is a real blood test!

This app has allowed me to be more conscious about the rate and amount of alcohol consumed. The graphs are incredibly helpful as they show how much alcohol will be in the blood stream after a duration that depends on factors entered in the profile. Other than having a device that can take a sample of blood and have an app analyze it, this app is a must for those who like to have a couple of drinks and know what levels affect your ability to function normally because everyone has a different tolerance level, a different metabolic rate, and a different liver function. I cannot say enough about this great app. It has helped me to be more responsible as a lover of fine wine and craft beer.

Great App

Love this app! It does everything I need it to and provides lots of control over the parameters. It did not match exactly to my personal breathalyzer, so I had to adjust my weight in my profile to try and synch the two. Bottom line is that you need to use this app as a rough guide. If you are thinking of driving, don't expect to use this app as a way of just staying under the legal limit. Even a personal breathalyzer can be out of calibration and give you a false reading. Use this app and a personal breathalyzer in tandem to stay well below the legal limit before you get behind the wheel, and you should be ok.
