I got this app for my new Ipod Touch 4g and it runs fine but because the lack of a actual compass or gps chip on the ipod the app cant locate the sats. You have to manually imput a known location for a sat to be able to pic up the sats on that part of the ark. For example If you allready have a dish pointed to 119 and want to know where is 61.5 you can choose the 119 sat and It will give you the sats from 129 to about 82, thats it. Im shure this is a great app for people with compass and gps on their device, but not for the Ipod Touch 4G. A waste of $10.00
