Publisher's Description

Photomator is designed from the ground up to build upon your Photos library. When you edit photos, changes sync with the Photos app automatically, your edits are nondestructively preserved by Photomator, and everything just works. But you can also easily edit images elsewhere on your device and even external locations like iCloud Drive and USB drives.
