So easy, you could use it drunk.

Quickly keep a tab on your drinking, with just a tap. Tabb helps you know what you drank, so you can make an informed decision--at the time you need it most.

Use it to split the tab, boast, or, ideally, to know how much you've drank so you don't over do it.

FREE, with no in-apps, ads, or crap like that. Just buy me a drink if you find it useful ;)

Coming soon to the Apple Watch, with new features such as a timer to know when you're safe to drive. Get it now for free, as the watch update will be a paid app -- and you'll get the upgrade for free.

Stay safe out there this St. Patrick's Day.
