Good app for sorting pics. – The Roll - Automatically organize and find the best photos in your camera roll Review

Update: Now works well on iPad too! Great idea. Just what I'm looking for. Worked on iPhone where I have a hundred pics BUT not on iPad where I have a couple thousand. Stuck at '0' photo scored til it crashes. Never makes any more progress.
