Sifterr is a simple, powerful photo organization app for organizing photos whenever you have a spare second. Create tags you care about -- maybe you want to be able to quickly find your "food" photos, or maybe you like browsing pictures of "cats" -- then swipe each photo in your library left or right. Photos swiped right have the tag applied, photos swiped left do not. You'll find a brand new album has been created for the tag you just created, and everything you've swiped right has been added!
Each swipe takes less than a second. Use Sifterr to organize your photos for just one or two minutes at a time, and within no time you'll have your entire photo library sifted!
