Drinkometer Free is an ad-supported version of Drinkometer, a simple application that tracks your drinks and estimates your blood alcohol concentration based on your drink history. It is simple enough that it won’t get in your way when you’re out having fun. Just tap the drink button every time you have a drink. Drinkometer will record the time you touched the button and use that time to estimate your blood alcohol concentration.

Many BAC calculators require you to enter a time you start drinking, or require you to remember the number of drinks you had at the end of the night. Not Drinkometer. As long as you tap the drink button every time you have a drink, Drinkometer will keep track of the number of drinks, the time and type of each drink, and calculate your BAC based on the drink information it stores.

Before you begin, just enter your weight and sex. Optionally configure your favorite drinks. When you're ready to use it, all you have to worry about is a single button to tap each time you have a drink. No more having to remember when your first drink was, or how many drinks you've had.

- 19 pre-defined drinks so you can find the drinks you commonly enjoy.
- Customized drink list so you'll never have to choose from more than a few of your favorites
- Simple interface so you won't have to futz with your phone while you're out with a group of friends--just tap a button.
- Move between drinks in your favorites list by swiping the drink button.

BAC calculation based on National Highway Traffic Safety methodology. Although the calculation methodology is sound, there are too many sources of uncertainty for this to be a basis for making medical decisions or evaluating your fitness to drive. The only 100% save decision is to never drink and drive.
