Typically, most photography apps incite you to snap lots (and we mean lots) of photos and share them socially with your pals and the world. One Memento also favours social sharing but in a hugely different way: the app can only upload one single photo to its everlasting online gallery before going bad, so choose wisely. Luckily, a 2 hour window after said upload remains to edit or retake the photo – because you don’t want that blurry picture of you passed out in front of a toilet accidentally immortalized on the interwebs. Your friends mightn’t be so lucky.

Act fast, since the gallery completes at 250 000 photos. Learn more at One Memento – $Free.
