The original version of the app allowed me to export the gpx files to a local folder on my phone. I could then email them and analyse them in Matlab etc. There does not appear to be an export option in the new app. How can I get access to the gpx files? Where are they stored?
You can download a session in four formats: Original file, GPX 1.0, GPX 1.1, and SBP.
To do so, open the session and scroll down to the Info section. Tap the anchor icon and select your preferred format.
