After a night of drinking there may be parts of an evening you forget - or moments you wish you could erase from your memory. But now there's an app that not only fills in these gaps in memory, it shares evidence of your drunken antics with your friends. Called Flashgap, all photos and videos taken using the app are added to a hidden album that only becomes visible the following day. The Flashgap app (pictured) is free for iOS and Android devices. Photos and videos taken on the app disappear into a hidden album after three seconds and only appear at midday the day after the event. All attendees of the event can see this album, and users can only delete photos they took themselves . Flashgap is free for iOS and Android  and was created by Julian Kabab. Before a night out, one user creates an event and becomes that event's host. They can then add friends to the event at any point until the event ends. During the night, photos and videos can be taken using the app and each shot lasts for just three seconds before it disappears.

The photos will be deleted by the Flashgap support team if the reason is legitimate, but this team doesn't have access to any of the images, the shots aren't stored on the Flashgap server and the support team can't view albums. Flashgap was  inspired by the end credits of 2009 film The Hangover. In the film, starring Bradley Cooper and Ed Helms, four friends go on a bachelor party to Las Vegas but lose the groom and have to retrace their steps to remember what happened. Mr Kabab, chief executive of Flashgap said: 'We experimented with GoPros on our heads during a night out and had such fun when reliving the footage and images the next day, that we really felt our idea had some substance. Only people who attended the event (attendees list pictured) can see the album, and users can only delete the photos they took themselves. Any photos deleted from the album are deleted from all users' accounts . Flashgap was inspired by the end credits of 2009 film The Hangover (Ed Helms as Stu is pictured left, Bradley Cooper as Phil is pictured centre and Zach Galifianakis as Alan is pictured right). During the film the trio go on a stag do to Las Vegas but lose the groom and have to retrace their steps to remember what happened . 'We can all relate to going out and being guilty of not remembering an awful lot and that's how Flashgap helps people out. 'We then watched The Hangover together and the ending credits show a series of photos from the guys' infamous night and that's what really triggered our thinking. 'The idea of people reviewing their antics from the previous night is such a powerful bonding experience and it is always interesting to see everyone else's perspective from the event. In essence, Flashgap allows users to be ready for yesterday.'
