[GPSNavX]

At this time there is no plans for such log book functionality. Apps are not designed to be everything, but the kitchen sink. Instead they are designed to one thing well. INavX focus is on real-time navigation. Instead I would prefer iNavX leverage another app for log book functionality such as iNavX does with AyeTides or other apps that support import of GPX or KML waypoints, routes, tracks. Think of apps more as widgets that work together.
