Every update seems to break or remove functionality. With the latest version 3.0, text is barely visible in the editor, some buttons are in chinese, other in english, but worst of all, the remote now only works for starting and stopping scroll. Adjusting the speed needs to be done on the iPad, in a menu so that you can’t actually see the result before exiting, and going back in front of the camera, and try again. The hardware is still good, but I am looking for a replacement app!
