FLB

App for the FlightlogBackup system where pilots can log their flights, track paper expirations, easy add hardcopy by taking photo and upload, check METAR and TAF, get airport information e.g. runways, frequencies and much more.

There is also a function where you can track your flight, which can run in the background while flying. Note: "Continued use of GPS running in the background can dramatically decrease battery life."
