Great work guys! We have started with premium also ( http://smartupz.com ) - but it's a very soft launch. We will go fully to market in about a month. We probably will share some figures after first quarter :)

I dropped by http://smartupz.com to find out more about your premium app. I found that the grammar was not correct in quite a few spots and would highly recommend you have someone proofread your copy. Not improving the copy will definitely impact your full launch in a very negative way. Having a crystal clear, engaging and gramatically correct message will go a long way to helping you extract people's hard earned money. Good luck with the launch!

Thank you very much for this point. We certainly will correct our pages!
