On the iPhone 6s+ the controls to photo and video editing are all stacked on top of each other in the left hand top corner. Not sure if this is just an iPhone thing but you cant use any of the features and so renders the app useless. Hopefully the developers get a fix to this pretty soon. Hate to throw away $20 on a toy for the app to not even work properly.
