Pretty weak effort... But nice idea. Id think they would have more pride Im the output. Complaints: Video content is short, too dark, and lacks audio. Seems more like an animated gif! Written part is too brief. So basically they dont explain in much detail and have exceedingly sketchy demonstrations. And as with other reviewers I had app crashes or freeze ups despite a modern iPhone 5 and LTE connection Come on guys - have some pride in your product. Id willingly pay for a something that truly offers value. Now I feel a bit scammed. Bummer.
