No functional point to this app

I was looking to create some pics of phrases in the sand for a slide show but you cant even save the "drawings" you create with this app. Whats the point of having a save button? And whats the point of this app - just to watch yourself draw in the sand? Pointless! There should be some sort of menu option or help prompt to figure out how to use this app, but again there doesnt appear to really be any functions to explain other than how to remove it from your phone. Delete!
