In version 3.0, We are ditching hamburger menu and going to use Tab-bar. Hamburger menu is one of controversial topic in UI/UX Flow.
In our case, During user testing we discovered only 35 percent users are only discovering hamburger menu, without which 90% functionality of our app can’t be discovered :-/ . Also user will have to leave context of a screen in order to access settings from hamburger menu. Which is one of worst nightmare for our users
TabBar is best replacement UI we were able to think of. Here is how new UI Looks like with Tab bar at bottom
