When I got my iPad I checked with my local avionics shop about software. The tech I spoke with has both Wing-X and Foreflight on his multiple iPads.
I tried both programs but went with Wing-X because where I live (Utah) there are lots of mountains and flying over mountains at night I find it handy to know where those mountains are.
As far as I can tell Wing-X has terrain (something I learned to appreciate before I got the iPad and was flying with an Garmin 560) but FF does not.
Yet reading the posts here and elsewhere it looks like FF is used by more pilots.
So now I'm wondering, does FF have terrain or do most pilots feel safe flying without it?
Clear skies,
