Most of us have come across a third-party app from the App Store at one time or another that has been built on an extremely confusing navigation structure and has managed to leave us all baffled. Does the app require a swipe to go back a step or does it have a simple back button on the navigation bar? Sometimes developers do get carried away and it can become confusing. Thankfully, Apple's native apps don't have this issue and seem to be extremely intuitive with the consistent placement of a back button on the left-hand side of the navigation bar that carries the title of the originating page.
