Cool Walls brings wallpapers, Lock Screen previews, matching themes, Themes Packs, Depth Wallpapers, Auto Wallpapers Changer,  app icons packs, and widgets and much much more together in one place. Whether you want a calm minimal background, a bold neon look, or something new for today, it is easy to explore and make it your own.

FIND A WALLPAPER YOU LOVE
Browse collections, discover popular designs, and search for a particular style or mood. Explore dark, abstract, nature, anime, and other wallpaper looks. Open a design for a closer view, save the ones you love, and return to your favorites whenever you are ready for a change.
PREVIEW YOUR LOCK SCREEN

See how a wallpaper looks with the time and Lock Screen layout before you save it. Adjust the framing to make the image fit your screen. For suitable images, explore a depth-style preview that brings the subject forward. You can choose a wallpaper with confidence instead of guessing how it will look once it is on your phone.
BUILD A MATCHING HOME SCREEN

A great wallpaper is only the beginning. Explore theme packs that bring together wallpapers, app icons, and widget art in complementary colors and styles. Choose a coordinated look or mix individual pieces to create a Home Screen that feels personal. Cool Walls also includes widgets you can add to your Home Screen.
MAKE THE DETAILS YOURS

Use the wallpaper studio to create a more complete look from a favorite image. Prepare matching art for your Lock Screen, Home Screen, and widgets, then save the pieces you want to use. Try different crops and arrangements until the result feels right. Some icon and widget setups may require the usual Phone setup steps after you save the artwork.
EXPLORE AT YOUR OWN PACE

Keep a collection of favorites for later, browse by category, and discover new designs when you want a refresh. You can start with a single wallpaper or put together a full theme. Cool Walls makes both feel approachable.
Some designs and tools may require an in-app purchase or a rewarded ad to unlock. Available wallpapers, categories, and theme packs can change as the collection is updated.
Your screen is the part of your Phone you see most often. Make it a place you enjoy looking at. Download Cool Walls, find a wallpaper that fits your mood, and give your Lock Screen and Home Screen a fresh look.
