IntelliDrink PRO - 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.

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."

"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.

IntelliDrink PRO - Blood Alcohol Content (BAC) Calculator Reviews


Needs to be updated  SneakK1NG  3 star

Having some issues with the iPhone 8 plus where the buttons on the edges of the screen aren’t responding. Other than that a really great app!


insanely accurate  echelon998  5 star

I've been testing it against a $100 legit breathalyzer. It's kinda wonky at very small amounts of alcohol but disturbingly accurate if you drink a decent amount. Like it keeps hitting within .01 accuracy by the end of the night. Very cool tool to have


Excellent app, could use just a couple more features.  teemcsee  4 star

Great, very useful. Would love to see a calendar view so you don't have to scroll forever to make corrections to prior dates and a way to custom sort the drink templates.

Sir Williams Awalt

Honestly, one of my most useful apps  Sir Williams Awalt  5 star

I live in a town where drinking and driving is unfortunately common. Every weekend there are random check points surrounding the valley that I live in because of how many drivers drink before getting behind the wheel of their car. I wanted an accurate way of keeping track of BAC levels without having to carry around a breathalyzer every time I decided to go out for a drink. This is the app. It's allowed me to go out and have drinks and not have to worry about being above the legal limit. I know my own personal limits, but laws don't care if you "Feel fine". But with this tool I can accurately gauge where I am with my BAC levels so that I don't have to worry about driving intoxicated.


Helpful if used correctly  Dexaryus  5 star

This is not something you use to avoid a DUI. If you're drinking you shouldn't be driving. This app is great for seeing not only how intoxicated you currently are, but how intoxicated you're going to be seeing as our bodies continue to process alcohol long after we've stopped drinking. I don't know how close the BAC numbers are to what you'd find if you took a breathalyser, especially because there's a lot of room for inconsistencies based on how individuals enter the drink data, however if I use the app consistently, then I know what the in app numbers mean to me. For me if I hit or will hit 1.3, I need to stop drinking or risk wakeing up in a dumpster. Also I can look ahead and see what my estimated BAC will be the next day when it's time to get ready for work, which is more valuable to me than what my BAC is right now.

Uncalm Symphony

Great app, very helpful  Uncalm Symphony  5 star

I like this app because it is helping keep my drinking in check as well as my level of alcohol. Great app.


Please make a watch app!  HillJohn  5 star

I love this app. Very easy to use and understand. Great layout. I think it would be great to have an Apple Watch app for this as it is sometimes inconvenient to enter drinks into the phone app in a social drinking setting. WaterMinder (water tracking app) has a great iPhone to Apple Watch integration. I hope this one will soon have the same!


Keeps me safe  Btru2005  5 star

I know my alcohol level a when I may drive. Accurate. Visually nice


Very nice app  Packratkid  5 star

Stop looking, this is the app you want  abelara  5 star

If you're looking for this kind of app, this is the one you want. Seriously look at all the star ratings, this app rocks. And it keeps getting better with more features. Enough said. (Pours another)


Great for tracking alcohol consumption  OldPhantom  5 star

This is a really nice app for tracking alcohol consumption. It allows you to create your own drinks and then track them. I would suggest trying the app before heading out for a night of partying. It was easier to set up my own drinks while I had access to the internet on another computer. Learning to add each drink was also a learning curve. I may just be slow! 😊. I do like the graph it shows to help gauge how the drinks will affect me after they are finished.


Very cool!  K12voltman  5 star

Just excellent. This is the only app I've ever paid for! When I'm out with friends trying new beers it's especially helpful because I can keep track of what I've had and have a better idea of when it's time to go home! Get it. It's worth it! The only thing I would change is to have the drink list be alphabetized or in numerical order when you open the app. Instead, when you add a new drink it puts it at the bottom of the list. After you drink that drink, it's at the top of the list, which is great. But all the drinks are just seemingly in no kind of order otherwise.


A MUST have!  Judgement75  5 star

I have sampled similar apps that pale in comparison. Precise, functional, and easy to use. The accuracy is unparalleled. The only app you will ever need for its kind!


Works Great!  JackFlack182  5 star

Been using this for a while now it it really works well. I highly recommend this for responsible beveraging. One bit of feedback is I would like to be able to change the accent color of the app and graph to something other than the purple.


Solid App - Next Steps  Phil87647  3 star

Good app w nice interface. Some great additions would be: 1) Apple Watch compatible 2) easier to say how long you took to drink, like a start and finish button rather than having to toggle in a sub menu 3) option to add drinking water as that also affects levels. Thank you for a nice app.

Awesome App  Texas roller girl  5 star

Pretty accurate and easy to use

Pretty tight  stupid nickname won't go away  5 star

It's not easy to make an interface simple and also effective. They seem to have done so. Very interesting to see what is going on in my liver...


Perfect!  GLRoth  5 star

This app is a great help to manage my drinking. It is convenient, easy to use, flexible and best of all informative. It lets you adjust drinks being entered to get accurate information. Then it shows a chart of your projected blood alcohol level so that you know how high it will go and when. I enter drinks before I drink to see what will happen and sometimes reduce the actual portion size of the drink to avoid going too far. Then I modify my entry to record what I actually had. Having the history is also extremely helpful. This app has changed my life. Bravo to the app developer. Buy this app.


Very Useful  MinnesotaMac  5 star

This app is worth the cost. Free apps do not come close. This app provides incredibly useful information about current state, time to sober and drinking patterns. It accomplished what I was looking for in an app.
