Worst human interface ever

There is a reason that we hate this app with a passion. This app has the worlds worst user interface. They have taken minimalism to the newest extreme: NO INTERFACE AT ALL. It is absolutely impossible to figure out this app. All we wanted to do was convert kilometers to miles and vice-versa, but it took us 10 minutes to figure out how to do that. After that, we wanted to "favorite" that conversion for the future, but after 30 minutes of trying to figure it out, we finally gave up. There arent even any buttons to get you to different screens in the app -- it expects you to just KNOW that you need to swipe. This app is truly the worst. We will be emailing Apple in the morning to request a refund for this useless and unfriendly app.
