Wallpapers for your computer are a dime a dozen.

But finding the perfect wallpaper for your mobile phone is trickier.

Especially if you set the bar high on art and design. Which, we know you do.

Quality. Not Quantity.

Vellum offers just that.

The app, for iOS, features a hand-picked selection of stunning wallpapers, all of which are intended for use on portrait-oriented displays such as the one on your iPhone.

The curated catalog is organized by theme, which makes it easy to find options that align with your idea of pretty.

If you have an Apple watch, Vellum lets you sync backgrounds between your watch and phone.

The app is free although there is the odd pop-up ad. You've been warned.
