Though a lot of us think we know our limit when it comes to how many drinks we can have and how sure we are in getting behind the wheel, we really don't.

This new device actually turns your smartphone into a Breathalyzer so you'll know for sure whether or not it's safe to drive.

Called the Breathometer, this is the world's first smartphone breathalyzer. The device plugs into your smartphone's headphone jack and after you download the accompanying app and secure the device, all you do is blow into the Breathometer to register your BAC.

If you're over the legal limit, the Breathometer app will pull up alternative transportation nearby and allows you to call a taxi with one push of a button. The app also tracks your past results so you can be sure to allow for the proper amount of time to pass before you think about getting behind the wheel.

Breathometer actually comes with a chain so you can hook it to your keys.

By using Breathometer, you'll now have the ability to help prevent accidents and keep yourself from running into trouble with the law.

Breathometer is $20 on their website.
