This release does not have a Play Store Description, so we grabbed one from version 4.5.2.159:

FAST, LIGHTWEIGHT AND MODERN! QuickPic is 90% smaller than other gallery apps, but packs more power than any of them, making it the best alternative Android gallery app for all your beloved photos!

QuickPic's smooth user experience is optimized for large screens and multiple finger gestures, and contains no ads or extra permissions. Colorful themes and a modern design helps you find your pictures in a fast and fun way. View thousands of your photos instantly in a high quality slideshow, and customize the folders you wish to include and exclude for more efficient scanning.

On top of this, our CM Cloud function offers speedy back up and restoration for photos - your photos are stored on industry leading Amazon servers to help you preserve all your precious memories securely.
