I used to be a Garmin Pilot guy  but have switched to Avare to save $70 or more a year. This is the best free aviation app for Android for many reasons including open source nature  smooth scrolling charts  multiple ADSB receiver support  chart overlay  and geo reference. I use a different radar app called MyRadar  because I don't like the low quality radar on Avare. I suppose the low quality is for smooth function and quick update. Overall  great job developers of Avare and thank you.
