Alcohoot is not only cool, it may also wind up saving a number of lives eventually.

Alcohoot is literally the world’s first smartphone breathalyzer. Before you start thinking you have to breathe on your phone to make it work, you don’t. There’s this cool little attachment that hooks up to your phone to see if you’ve had too much to drink. In experiments and labs, the results have been accurate, which means that it should pretty well gauge how much you’re lying to the officer about how much alcohol you’ve inhaled that evening, too.

But the coolness factor doesn’t stop there. If you’re lazy and don’t want to breathe into this little thing that tells you how drunk you are (hint: if you can’t manage to do it, you’re probably too drunk to drive home), you can tell your phone how many drinks you’ve had – and of what – to see when you will be able to drive again. It tracks your BAC as the night progresses, and this feature is only enhanced by the breathalyzer gadget you need for the full functionality of this app.

So you’re seriously drunk, right, and the unit tells you so. You tell it you plan on driving home and you know what it does? It goes all Mom on you and tells you to simply press a button instead. That button calls the nearest available cab, makes the reservation for you, tells the cap driver where you are, and bam! Fifteen minutes later you hop in a taxi, and you’ve spare your life and your car from some vomit, too.

If you don’t want it to call a cab for you, that’s OK, too. It’ll give you a list of local restaurants where you can snack and drink water until your head clears up a little. We’ve all been at that point where we walk into our favorite restaurant and realize that we didn’t actually walk in, we broke in, and the place is empty. And now there’s some puke on the floor, too. Damn. That’s always sucky, especially when there’s an alarm system. Anyway, the app tells you which restaurants are open so that there’s someone there to hold your hair back while you take advantage of the bathroom.

So this app doesn’t just breathalyze. It even tells you how drunk you probably are dependent on your weight, height and gender, something that police breathalyzers don’t really do all that well.  That’s kinda cool, especially when you have to drive home on your own and you really want to know how drunk you actually are.

By far, the most badass thing about this app is that it will track your drinking over time. If you drink a lot and use the app a lot, it will keep track of a calendar for you that tells you just how often you’re out with your friends forgetting all your troubles. Some of you may not want to use this particular feature if you don’t want to know.

The app has already been called “an innovative approach to combating drunk driving,” and I have to agree. I’m usually a smartass when it comes to stupid things like this, but this particular app can save some serious lives, not to mention boost the economy a little by paying taxi drivers who could use a little more business. In short, this app makes me happy. And if you drink a lot, this app should make you happy, too. Two words of advice: USE IT.
