The Tabbedout app, available for Android and iOS devices, is slick and simple to use.

A location-based search feature lets users find bars and restaurants nearby that accept Tabbedout for payment -- some even offer discounts for using the app.

A social media feature lets users tell friends and followers via Facebook and Twitter where they are.

Opening a tab is as simple as clicking one button. The app is linked to a payment card so closing a tap at a bar is quick and painless. (No guarantee the day after will be painless).

The admin screen lets users easily add payment cards and set up security to lock the app. It even provides a "CabbedOut" feature in case someone needs some help getting home.
