Anyone have any recommendations for worthwhile apps to download to an i-Phone, i-Pad or i-Touch?

I'm picking up a new i-Touch tomorrow and am searching for useful apps, especially those of particular interest to the ETS community.

In my i-Tunes library, I have iTorch4 and Survival Guide. And just found a Coleman Lantern app that I downloaded for old time's sake.

Am trying to sort through the many options for a compass, many of which I gather aren't of much use with the i-Touch.

Need a First-Aid app.


Free is nice but am also looking for good value in paid apps.
