I have the PC and Mac version and while this program gives you the same technical data it takes little advantage of the iPad nor the services available in the iOS (e.g. you have to enter your Lat/Long when iOS can provide that data). It is pretty much a crude port into the iOS environment. Its saving grace is that it has all the propagation data you want to look at while contesting and DXing and the grey line chart, while crude in the context of a graphic, still portrays the data in a useful format. Combine with the iPads compact size, it is a useful addition to shack. Given this is a version 1 product, I hope to see improvements and better integration into the iOS environment.
