Excellent  but... Excellent app  with one small issue that stops the app being perfect. If I start up the app  or reboot the phone  logging doesn't automatically begin. You have to go into the app and press play/start for the logging. How about making it possible to auto start the logging  not just the app? Also  if the power save is on  GPS gets turned off. It would be nice if the app could reactivate when it turns back on again?
