Flightwise Flight Planner app for iPhone and iPad

Flightwise FlightPlanner & Chart Explorer is an aviation application designed for pilots. With it, you can create and file flight plans, view aviation charts and weather, and lookup airport information.

FlightPlanner has both VFR and IFR Enroute (low-altitude and high-altitude) charts, and allows overlays with aviation-specific conditions, including AIRMETs, SIGMETs, PIREPs, TFRs, and echo tops. It also includes general-purpose weather radar and wind speed maps.

After filing your flight plan, you can also activate and close your flight from within the app; the same flightplan can be easily reused, and you can easily file the reciprocal plan to get back home.

Unlike other apps with these features, FlightPlanner is 100% free, with no subscription fees!
