Wallper

Wallper turns your own videos and photos into a live wallpaper for your home and lock screens. Pick a clip, frame it, trim it, and it plays behind your apps. Wallper also comes with a built-in 3D black hole, drawn in real time, with the light of the stars bent by its gravity.

YOUR VIDEOS, FRAMED FOR YOUR SCREEN
• Pick a video or a photo in Android's photo picker. Wallper sees only what you pick.
• Move and zoom a crop frame shaped like your screen.
• Trim the clip on a timeline you can scrub, or set its start and end at the playhead with one tap.
• Keep the original and edit it later, or save it optimised: only the part you picked, already cropped and trimmed. It takes less space and is easier on the battery.
• Original videos pan as you swipe between home screen pages.

PLAYBACK YOUR WAY
• Loop: plays over and over, going on where it stopped.
• Loop from the start: starts over each time you turn on the screen.
• Play once: plays from the start when you turn on the screen, then stays on its last frame. Easiest on the battery.

A BLACK HOLE ON YOUR HOME SCREEN
• The stars and the Milky Way bend around the black hole the way they do in physics, as a gravitational lens.
• A glowing disk of matter turns around it. The side that moves towards you shines brighter and bluer, as the Doppler effect makes it.
• The view follows the tilt of your phone and turns a little as you swipe between home screens.
• Make it yours: quality, camera tilt, disk speed and brightness, stars, glow, the strength of the lens and more, with a live preview.
The black hole needs OpenGL ES 3.0. On phones without it, it's hidden.

EASY ON THE BATTERY
• Nothing plays while the wallpaper is hidden behind an app or the screen is off.
• In Battery Saver and when the phone gets hot, videos pause (you can turn this off) and the black hole stands still, moving only when you tilt or swipe.

RELIABLE
• Your wallpaper is there right after a restart, even before you unlock the phone.
• If the phone's video decoder stalls, Wallper gets the video going again by itself instead of leaving a black screen.

PRIVATE
• Your videos and photos never leave your phone.
• No account and no ads.
• Usage statistics and crash reports help improve Wallper. You can turn them off in the settings at any time.

ALSO
• Light and dark themes, and your phone's own colours (Material You).
• See how much space each wallpaper takes, and delete what you don't need.
• Something wrong? Send the app's log from the settings to help fix it.
