Hi Charlie.
No worries on "the learning curve".
We can dismiss building it with iOS since there is no direct way to get to the necessary internal protocols and no access to the SDR via USB. That leaves Android. ForeFlight does not run on Android.
I have 3 apps on my phone that use the USB OTG feature to receive the ADS-B data from a SDR (one of the cheap ones). Avare, FIS-B Free, Avare ADSB Pro (different developer than the Avare above). There are Android solutions out there. Avare would be great but I can't get the USB OTG function on my Nexus 7 without rooting it (other Android tables work very well though).
