Stash or Trash is a photo cleanup app that works like Tinder for your
camera roll. Swipe right to keep a photo, swipe left to delete it. The
app automatically finds duplicates, blurry shots, dark photos, and
screenshots so you don't have to scroll through thousands of photos
yourself. Everything runs entirely on your phone with no accounts, no
uploads, and no data collection. It takes a chore everyone puts off and
makes it fast and oddly satisfying.
