About this app

Your homescreen and lockscreen deserve some variety. This app uses pictures from Reddit for an infinite selection of high resolution wallpapers, based on your favorite categories and subreddits. The app runs in the background and automatically updates your wallpapers for you. With customizable schedules from hourly to daily, you can have an automatic slideshow for your phone's backgrounds. The settings are heavily customizable, with tons of options such as post filtering, rank sorting, image effects, and preset categories.

You’ll never see the same image twice. You can select as many categories and topics as you wish, and the app will automatically and randomly pick the best one.

Over 10,000,000 images served and counting. Featured on Gizmodo BR, Android Police, XDA, and many more.

Features »
Automatic wallpapers.
Schedule how often the app will auto-update your phone's homescreen or lockscreen background. If you don't like the wallpaper that was picked, you can easily change it to another with a single tap or gesture.
Multi-subreddits.
Choose as many subreddits as you wish for unlimited wallpaper variety. Don't know which subreddits to use? The app includes a hand-picked list to help build your photo sources - such as nature, imaginarylandscapes, and more. You can even find device-specific subreddits for AMOLED displays, notch cutouts, and camera cutouts - such as /r/amoledbackgrounds and /r/PixelHolePunch.
Image effects & filters.
Personalize your wallpaper's brightness, blur, or cropping - the app can automatically apply these image effects based on your preference.
Content filters & sorting.
You can filter the wallpapers the app will select. Filter images by post upvotes, image resolution, widescreen or tablet size, NSFW, and more.
Shortcut gestures and widgets.
Get new wallpapers instantly with one tap. Add shortcuts to your homescreen, quick settings menu, or with advanced gestures from Nova Launcher and other custom launchers.
Image History.
Never lose a great image. You can re-apply previous wallpapers from right inside the app, or download them to your device's storage automatically.
Tasker Integration.
Are you an advanced user? This app works with Tasker to change your background on custom triggers. Whether you want a new background whenever you unlock your phone, when you arrive home, or switch Wi-Fi networks, this app has you covered. (Requires the separate Tasker app)
Battery efficient and storage friendly.
Your email app probably uses more battery than this one will. This app updates your wallpaper within seconds and the app never clutters up your phone's storage space.
