This app has thus far proved to be a nearly faultless choice particularly when in "rotation" mode after selecting from the 'endless' SUPERIOR QUALITY Nature, Animals ETC. Photos, Images, Art and so on. PERFECT long-cycle "screensaver." One of our testers borrowed a test device with her 1176 choices for a night (=year)!! WE still DO GREATLY DISLIKE the crowded selection menu which really needs to be condensed yet our NET Results: DO CHECK OUT THIS PUPPY & smile a while/fall asleep in 'rotation.'
