Been using DroidEFB: EFB for Pilots (US) for a couple months now. It’s basically an app for pilots that’s got all the essential tools you need – charts, weather, fuel prices, and more. Pretty solid if you’re a general aviation pilot.
Here’s what you can do: you can cache maps and airport diagrams for offline use, file flight plans right from the app, and get live ADS-B traffic and weather. There’s also a really handy fuel price lookup tool – it’s got data from FlightAware so you can find the cheapest fuel before you take off.
Look, if you’re a pilot who wants a one-stop-shop for all your flight planning needs, you’ll probably like this. It’s not perfect – the interface can be a little clunky at times – but overall it does the job. Worth checking out if you want a professional-grade EFB app without the subscription fees.
