Seen 'The Hangover', we've all had a few nights like that!
'Track my drunk night' allows you to wake up in the morning, pick up you phone and see where you went, how long you stayed, how far you walked along with 'pub time'. It'll even tell you if you got home (which I'd hope you know)......

Then post your expolits on facebook, see who lasted the longest, walked the furthest or went on the most exotic route.

Please note:
Continued use of GPS running in the background can dramatically decrease battery life.

This app monitors battery level, if it falls below 20% GPS tracking is disabled and the current route data is saved.
Users will also be prompted if battery level is not considered high enough to complete the duration specified by the user at the start of tracking.
