We often have too many photos. They often eat up either the storage space on the phone, or the iCloud space quota. Even if we have unlimited storage, they still create a lot of noise, making it harder to pick the best photos.

This app provides the fastest way to declutter the Photos app. You can either:

(1) just delete all photos that are not favorited (way of the ultimate zen / minimalist)

(2) move all photos that are not favorited to an album call "Not Favorite". Then you can easily select all of them, and back them up to an external drive, or another app/service, and then delete them from Photos.

After that, you will have a clean view in the photos app, with nothing but the best pictures.

And as a perk, next time you can just spam the shutter button and take as many photos you'd like. Because now you have the fastest tool to remove all the experimental pictures that you don't need to keep.

Why use "favorite" to determine what to keep?

Because it's the easiest and fast way to mark photos that you want to keep. It's done in the Photos app, which is the best photo browser. You can go through photos and do all the editing and mark the favorites in one go.
