I use motionx gps app as a backup to my gps. Map and compas still always come.

Gear lists are highly personalized, are you interested in ultra light hiking or are you willing to carry more weight ?. Lots of them on the web, download them all, take what you want from each one. Mine are all on paper, I like to leave a list of what I have with my itinerary but you could get a make your own checklist app and enter the data there.
