Not usable for me

I was probably one of the first to buy it maybe three years ago, but Ive never used it once.

Since I use the ipad in landscape mode in the cockpit, and my head doesnt swivel 90 degrees well, I just cant use it.

Unless you are only going to use it on the iphone, which seems very difficult since the places to touch are so small, Id suggest NOT spending any money on this junk.

Since it is difficult to touch the right places on the tiny iphone screen (which I do have), it would actually be dangerous to use this in turbulence - taking your attention away from flying the plane for too long while you try to touch it in the right place. If youre using a checklist, something is happening in the cockpit that requires you to complete tasks - not mess with horrible software.
