[aprssig] iPhone APRS app?

[Lynn W. Deffenbaugh (Mr)]

There's an bike event coming up this weekend and a few members of our 
local club are volunteering support for the first time, but they've 
never done APRS and only have iPhones.  Can anyone provide me with 
pointers to what's available on that platform?  I've already ruled out 
the aprs.fi app because net control will only be using local APRS 
clients, not the aprs.fi web site.

please send them privately to me and not the list.
