IntelliDrink LITE - Blood Alcohol Content (BAC) Calculator

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.

The LITE version has advertising and limits you to adding no more than 3 drinks per day. PRO features include Multi-User Support, Custom Drink Templates and User Statistics. PRO features can be accessed via In-App Purchases or the PRO version.

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 Ive 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."

"This app is simply amazing. 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.

- Apple HealthKit integration. Can read age, weight, height, sex and write BAC and calories.

- 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’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.
