Change your friends'
phone wallpaper.
Send a photo tagged #wallpaper and it quietly lands on a friend's iPhone Lock Screen — no app to open. They send one back, and your phones fill up with each other.
Step 1 of 3
Add the Yallpaper Shortcut
Yallpaper runs on one tiny iPhone Shortcut. It watches for #wallpaper messages and sets the photo as your Lock Screen — hands-free.
Step 2 of 3
Bring your friends
Yallpaper works between friends who both have the shortcut. Send them this page so they can set it up too — then you can swap wallpapers back and forth.
Step 3 of 3
Pick a wallpaper
Choose a photo or snap a selfie — we'll size it for a Lock Screen.
Last step
Send it
Share this with a friend who has the shortcut. Their Lock Screen updates the moment they get it.
