i had a talk with some devs, and they said its quite a port, so the algos are the same than bias ios,but the app wiull have more features and some surprise (they say) in the near future update.......i would tell them "so you are willing me to pay 99$ for a mere port of a 15$ ios app on my pc?" but then i tought they will maybe learn the lesson the hardest way..... ps:now bias pc is 149 instead of 99.......99 was the launch price for the 1st days.................
