Hello!! You'll mostly have to do some digging, but almost all profile codes are F2U & Mobile friendly! Here's a few of my personal faves:
Codes By Ronnie:
- https://toyhou.se/6661907.-users-simple-bits || short "bite-sized" layouts
- https://toyhou.se/6662994.-user-howdy || small block with neat little sections!

There are plenty of others out there, It just takes a good search to find them! And if those don't work out, you can always convert a character profile into a user one!!
