You spend a long time staring at your smartphone screen, so don't settle for a backdrop image that's staid and dull. These Android and iOS apps bring a wealth of superb ready-to-go images right to your handset in an instant, so the only problem you'll have is choosing your favourites.
1) 500 Firepaper
Any wallpaper app is only as good as the pictures it can find for you, and that's the strength of 500 Wallpaper. It picks images from the outstanding collections posted on 500px and applies them as your phone's backgrounds. The app lets you choose which 500px categories you see and which feeds the images are pulled from. [Android]
Wlppr comes packed with a constantly growing collection of spectacular satellite imagery taken from space. Images range from alien-looking mountain tops to some of the most densely populated cities on Earth. You get dozens of images for free and others can be unlocked through in-app payments or by sharing your love for the app on social media. [iOS]
3. Wallrox Wallpapers
This is a great choice if you're into Material Design or ultra high-definition images (or both). The wallpapers are stored at a resolution of 3,200 pixel 2,560 pixels to give you the sharpest possible image. It's slick and simple to use, and you have the option of cropping pictures before applying them. [Android]
4. Pimp Your Screen
You have to pay a couple of dollars for Pimp Your Screen, but it's totally worth the small price. The app lets you design your own home and lock screens, complete with images, text, and more. There are ten categories of wallpaper to browse through, and a handy preview function that adds an icon overlay. [iOS]
5. Best Wallpapers QHD
This isn't the most sophisticated app in our round-up, but it's packed with fantastic-looking, high-resolution images to adorn your mobile phone's home screens. The app lets you browse by category, tag, popularity and more (the Editor's Choice section is definitely worth a look), and wallpapers can be applied with a single tap. [Android]
6. 10000+ Wallpapers
Sure, that 10K figure is an impressive one, but there's plenty more to the app. For example, it features a clever search system, the ability to bring up recommended images that are similar to ones you already like the look of, and an easy-to-use preview tool. If you can't find a bunch of images you like in this app then you're never going to be satisfied. [iOS]
Wonderwall sticks to the basics — the basics being top-notch backgrounds for your Android devices and an intuitive browsing system. You can have pictures change automatically, if you want, and there's a simple bookmarking feature to keep track of your favourites too. Most importantly the wallpapers look amazing.
