I have this on my MacBook, iPhone, and iPad

This has got to be the only app that I use on all of my devices. All of the pictures are so high quality, high resolution, and completely transform any of your devices. Here’s the difference between this app and other wallpaper apps: all of the artwork is about the same quality (there are no varying qualities when you click through), the app is very easy to navigate, and everything is “cut” perfectly to fit your device (no awkward cropping, stretching, and shrinking of the wallpapers required). I’ve had this app on my iPad for years, and I’ve tried some other similar apps out—only to delete them and come back to this one. It’s just the highest quality you can find.
