Buggy as hell. After swiping through a month, it asked me if I wanted to keep or delete. After clicking "keep", it deleted them all. -_-
Then I clicked the calendar icon, and it just went to my iPhone desktop.
Deleting immediately!
Sometimes you see a description of an app and you think: 'This is brilliant, I need it'. This is one of them. I love keeping my library in check and to get rid of all the quick snaps I dont want to keep. Lovely idea!
