How can I change my wallpaper daily? I am trying to set my android device's background image to change daily. I have been using Google's Wallpaper app but recently have been getting repeats. I am trying to use unsplash source instead. Is there a way I can do this, without root, using unsplash source?
There's an app called Casualis this app let's you do exactly what you're looking for.

Features:


Set a random wallpaper every 1/3/6/12 hours or every 1/3/7 days, at the time you prefer;
Choose a wallpaper manually among over 3000 high-resolution images or use your own images;
Set a random wallpaper using the widget or with a shake of your smartphone;
Apply random effects to the wallpapers;
Customize Casualis by buying extra functionalities.


I never used the app, but it seems to have some good reviews
