Love the idea, app looks great, but I wish there were better options for adjusting the image rather than zooming in and out. For most of my pictures, I need to rotate them a bit in order for the face to line up properly, and if I cant do it within the app it seems like a hassle so I just dont bother. Id use this app if that was an option.
