observations from field test of Route Viewer App

I tested out Route Viewer on a 2.5 mile circular walk I do regulary and could not get it to work.

You mean the GPS Recorder, or something else? Could you tell me the app and what steps you did, as I've used the GPS Recorder many times an it's worked great for me.

Is there a way of getting console.log() to send output a phone App ?

Yep, just go to https://www.espruino.com/ide/ on your phone :)
