The 'Drunk Mode' app allows you to find your drunk friends via GPS with the 'Find My Drunk' feature.
The app also 'hides' selected phone contacts when the user wants to get drunk - meaning those contacts cannot be called for twelve hours.
The 'Breadcrumbs' feature uses your phone's GPS to tell you where you were last night.
For the 'Breadcrumbs' feature to work the GPS must be running throughout the event or gathering so make sure your phone is fully charged before leaving the house.
The app was released in 2013 and has become a slow-burning success with over 100,000 downloads.
An update to the app in late 2014 allows Android users to recover sent Snapchats, a feature which will be available for iOS soon.
The developer team say that several new features are also in the works including finding the best deals in your area and booking you a lift home.
The app is available on iPhone and Android.
