Doesn't work Tried this because My Tracks is being shut down (Why???). Just couldn't get it to do anything (Nexus 5  6.0.1). It offers Start Logging & Stop Logging buttons  but they don't appear to do anything. App seems to have lots of settings  but doesn't have sensible defaults set. E.g. In My Tracks  it works straight away  saves a file  prompts you for description text  saves it  and shows picture of your route. App needs defaults that work!
