Frustration with the phoneskope app

I need help. This app has helped me shooting thru the side shot because you can select the lens HOWEVER using the APP is driving me nuts. Specifically because I don’t seem to be able or to understand how to save the settings. If I change ANYTHING go from photo to video or make any change I’m loosing all other setting that I want to keep. The rotation is particularly hard to set and if I change any thing it’s gone. There HAS to be away to set and keep. Be damned if I can figure it. 


Also what’s the difference between “Live Photo” and “still photo”. What is GIF mode?
