Oudie Live is an app that Bluetooths to your Oudie and sends position data packets to SeeYou Cloud, Soaring Spot or Livetrack24, whichever you choose to use. Works great as long as your phone can see a cell tower.

I use Oudie Live as a backup to my PLB in case I am unable to operate it. You also need an extra battery to avoid depleting the phone battery.

XCSoar offers a similar facility.
