Save to iphone for use in other apps – PixSort -- tag and organize your photos Review

Nice app to organize photos. I would like to be able to save the info back to my phone so I could easily identify and use photos in other editing apps. I would like to be able to flag photos quickly for: deleting, and for further editing/processing, etc in other apps like Photoshop or Snapseed.
