Don't know if Foreflight works on Androids or not, but Avare is free,
has current sectionals, IFR low and high charts, approach procedures,
TFRs, airport guide, flight planning..., etc. Created by a pilot for
pilots and you don't need anything special (licenses) other than an
Android device. Neither, do you need any kind of connection once you've
downloaded the data to your device.
