I was annoyed how a perfectly nice phone wallpaper did not really look great when my Fold 7 was opened. So I created an app to display the main background image in the center and fill in the background with other photos from your folder. You can easily swap all photos on a timer or at the push of a button, or even just swap out the background images. There's also a "Fold" option where you can, when the phone is closed, just display one image, but when it opens, display the collage effect. It's good for your wallpapers, or photo collections.
There's also other effects you can toggle (rain, blur, background image desaturation, etc.). Gestures, dockable shortcuts, widgets make it very easy to control.
This is shameless self-promotion, but I genuinely use the app and made it because I felt the Fold could use it. I checked the rules on this subreddit and I didn't see any rules around it, so sorry if this is forbidden. But I hope you enjoy the app. The app also has paid features but if anybody really cares I will DM them a key anyways.
Thanks for your time!
