I had the free app and you could only have 6 vids, so I upgraded, thinking I would get more vids and a better camera, but it was only the case for being able to let me have more videos, and the video that is on the screen where you can look at what it looks like? Its complete bull crap, if I where you, keep the free one, and if you want to have more vids, simply save them to your camera roll and then delete it on the app, and I will give this a 1 star rating because Im not sure if it will let me go into negative stars
