Bookmark - Another book tracker... hear me out!

This is my first app ever. My wife wanted a book tracker app that she could mold her way without having to pay a subscription to get new features and track her reading. She reads a combination of physical and kindle books (she owns both copies of the same book) so she uses this tracker to mainly keep track of page count. If she got to page 125 in the physical book, she can easily find it on the Kindle app when she goes to read at school or something.

Anyways, the point of this app is to be clean, simple and free.

Right now it's pretty bare bones but I would love some feedback and suggestions if you have any! It is currently only available on iOS, so sorry about that Android users... but if I get good enough demand I might learn how to import it then.

Here is the Testflight public link if you would like to test it out!

Thank you!
