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.

The IGCdroid app (for Android phones) both generates a backup IGC flight log file and sends the logged data every couple of minutes to glideport.aero (where cellphone data service is available, which works well enough around here). This works for real-time tracking for fun and some S&R value. Almost free, runs independently of all other systems in the glider, and only uses about 1/4 of my phone's battery on a 5-hour flight. With that *and* a PLB I feel reasonably covered.
