I am looking at getting the Samsung Galaxy Tab S and would like to know what chart software everyone uses on their android tablets. Normally I like to use the FAA charts at https://www.faa.gov/air_traffic/flight_info/aeronav/digital_products/dtpp/search/ when I am flying in the US or its territories and when I am flying outside of the US I use my subscription to Navigraph charts. I know Navigraph has software that can be used on android tablets however I like the format of the FAA charts, not to mention Navigraph does not have nearly as many US charts as the FAA website. The only other place I have found would be Jeppesen but their IFR charts are really expensive.

I have a samsung tablet.

Just download the adobe reader, then use your browser to download .pdf files from Airnav.com and save them to the tablet. Then just fire up the Adobe reader when you need a chart.

Simple, works great.

Give it a try.

I use FltPln GO from FltPln.com on my 7" and 10" tblets. Its free and has Sectionals, IFR Hi and LOW, as well as Terminal ARea charts, along with ILS Procedurers for airports.  Got me at the Google Play store, search "FLTPLN GO"
