CleanUp - Photo Album Editor is a free iPhone app developed by Jeff Frese. It falls under the category of Multimedia and aims to help users clean up their photo library quickly and easily.

With CleanUp, users can swipe left and right to compare photos and swipe up to delete the ones they don't need. The app is designed to make the process of cleaning up a photo library efficient and effective.

CleanUp recognizes that most users have thousands of photos on their phones, and a significant portion of them are mediocre and can be deleted. The app encourages users to delete 90% of their photos, keeping only the 100 best ones. By doing so, users can free up space on their devices, clean up their photo libraries, and improve their photography skills.

If you're looking to declutter your photo collection and become a better photographer, CleanUp - Photo Album Editor is a useful tool to have.
