While looking for a PixelFed app (never found one), but I found something called Okuna (Used to be called OpenBook, but since Facebook owns the word book, legal blah blah blah name was changed to Okuna.)

It seems to be in early stages of development and its not even fully public yet. To access it early you must pay $11 USD. It seems like a cool privacy social media. The app does contain Google analytics sadly.
