Aviation Waypoint Navigation

GPS point-to-point navigator for pilots or passengers of aircraft, ship, train or other journeys which are direct to a destination or via a series of Waypoints.

Only requires GPS connectivity so AWN works in "Flight mode".
If you do have an Internet connection then you can see your current location on OpenStreetMaps (no subscription required).

Maintain a list of Waypoints, which you can enter into the application, import from spreadsheet or download from the Internet
Select a Waypoint for immediate "Go to" navigation or set current location as waypoint for "Man overboard" situations.

Build a list of regularly used Routes from the Waypoints then select a Route to navigate.

Automatic Route Waypoint selection during Navigation.
Route waypoints are listed in the Navigation screen in order of distance (nearest first) from your current location (except that the top item will be the closest Waypoint which is both On Route and Ahead).
Waypoints will therefore sort themselves when you pass over a waypoint or when you wish to travel a route in reverse.
Temporarily switch "On Route" or "Off Route" priority of route waypoints during Navigation for instance to route to a reporting point or destination diversion.
