It runs on an iPhone, or iPad. I didn't buy it, because we don't have ADS-B anywhere around here.

it's really slick. VFR and IFR enroute charts, all approach plates, stuff like that. it also has a scratch pad, for copying down clearances, and radar.

For ForeFlight, all the charts, VFR and IFR and all the approach plates are $74 per year. That's ALL, as in all the continental US.
