Flashgap

https://www.flashgap.com/ --- Flashgap is a French mobile app launched in December 2014. The app - originally branded as "the Hangover" app - allows you to create a (public or private) photo album during parties or events. What’s so different about the Flashgap experience? All contents disappear after 3 seconds. The full album only reappears at 12pm the next day, for better... or for worse! So, are you ready for tomorrow ?
