Navigation in the app goes against ios patterns – McMaster-Carr Review

I wish designers and developers of this app can follow Apple’s HIG instead of inventing its own bad wheel. Definitely not a fan of the “back” button at the right bottom corner of the screen. Please use standard navigation view controller provided by the system. Back button should be at the top left corner. Be a nice citizen of the platform you are working with. We aren’t android users here. We value system integrity and quality.
