Swan is an exquisite wallpaper application, dedicated to freeing you from the trouble of "which wallpaper I use today".
Filtering algorithm: We screen good-looking pictures from free material websites in the background every day, and then the operators filter them again and put them on the app.
Your luck: We provide the "Luck" function, you only need to click the button to get today's wallpaper picture from the picture we have prepared, generally speaking, the result is different every time.
