DOES NOT WORK!!!

Does not run on my 2011 MBP 2.5 GHz 16GB 1600 MHz DDR3 (Mavericks 10.9.1)

Works on iPhone only.

On my mac, it just bounces its icon in the dock for about 30 seconds then stops bouncing.
The only option is to Force Close.

I recommend not buying this app until it’s fixed.
I’ll be the first to praise it if it works.
