It all works extremely well right now. Obtaining the software allows you to run it on both an iPhone and iPad at the same time. It works identically on the iPhone except for the smaller screen. The data is identical.
Tap in the (i) icon in the bottom right, select ActiveCaptain, and you can Update your data to retrieve all marker information and reviews that have been changed since the last synchronization.
And of course it follows your position optionally locking your GPS position in the center of the screen, turning the display as you turn.
This is way, way cool...
