For android the app is IGCDroid. I've been using that along with Delorme InReach. IGCDroid works great too. It's very simple to start it up and just let it run. The beauty of the phone app is that it provides fine resolution mapping and it's practically free. The InReach unit provides coverage where there isn't cell service. In the west, there's a lot of territory where cell phones don't work; I think, less so in the east. I've added a power port to my panel so that I don't have to be concerned about draining the phone battery. Having the phone running has some other benefits as well.

I'm a big fan of IGC droid for what it's capable of. I run it off my Samsung smart phone (Galaxy note 3, I run it in the background while also running XCSoar). In addition to what was already mentioned, once it detects you've taken off it can send an email to a preset email address notifying that you've taken off and will do the same with landing. It can also send to an email address your GPS coordinates/pin on a map of where you are once you've landed. I also use it to track flights for OLC submissions.
What type of panel port due you have? I'm looking into options but currently I have a rechargeable power pack that I use and have had no problems with 5+hr flights.
