We want to have users navigate our app using a side menu.
Once a user leaves main app pages, the menu button (in top left corner of nav) would change to a back button.
However, the content of our app is prolific enough that I think we also need a constantly present menu button in top nav to get back home, or to a main page. Users could end up tapping "back" forever without a global menu button. But we definitely need a back button as well.
Can anyone think of a viable solution? Has anyone seen alternative nav options, possibly like this:
Thank you for any help you might have!
