FLASHGAP

Flashgap is the time-delayed photo-sharing app inspired by the movie ‘The Hangover.' During an event, it is impossible to see or remember everything. With Flashgap your friends will always be there to remind you. Available for iOS and Android, in many ways Flashgap resembles other collaborative photo album-sharing apps. It enables you to create a photo album tied to an event, invite others to contribute their photos, and share the resulting album with the group as a whole. However, all of the photos remain hidden until midday the following day, when they unlock so that the previous night’s horrors can be re-lived by all. (TechCrunch)
