Very useful. Just needs one thing for iPhone which it has for iPad. Thats side by side. I use another app V1 for side by side. Yeah its small but you can see it fine so the iPhone version could really use it and I wouldnt have to use the other app especially since V1 doesnt have zoom which I really like about coach my video.
