This is a link to a FREE phone app that you can use to record and play back your game in Slow Motion. I got the link from a golf instructor named Clay Ballard. He has an online golf instructional site that is very good and not at all expensive if you sign up the the year at a time option. Or it's around $8..00 for a month trail. I just got the link to the app so I have NOT had a chance to download it nor use it, so I can not give you a hands on report yet. Check it our and see what you think. Hard to beet free price.
