Outstanding app. Very intuitive. Excellent layout. Approach plates are instantly accessible and you can switch back to your enroute or terminal area chart with one tap. Long-press anywhere on the map and you get a pop-up with nearest navaids  airspace  etc. Put this app on two tablets  with a full set of charts and plates on each  and you can safely and confidently fly anywhere in the country  IFR or VFR.
