I’d prefer to have the tab bar on the bottom on mobile.

It took me a while to find the three-dot menu because it’s not in the top-right hand corner of the screen; instead, it’s underneath the tab bar.

Moving the tab bar to the bottom would make it easier to reach with my thumb, would be consistent with how native iOS apps work, and would place the three-dot menu in the top-right hand corner of the screen, which is a pattern I’m very used to.
