Perfect app - an example of great programming that does this task brilliantly. This is a superbly easy way to transfer gpx files downloaded on your hone from eg Strava, ridewithgpx etc using this app and the corresponding ConnectIQ app on your Garmin. I am using Android Marshmallow an the Garmin Edge 820.
