Transponder

Transponder app for GPS tracking of sailboats

Transponder app for yacht race tracking at Sailtracker.net. Transponder uses your Android phone to communicate realtime position and performance data to the Sailtracker website where a race can be watched live or later via playback. This version of the app only works with Sailtracker. The Pro version allows connections to other tracking sites.

Note: continued use of GPS running in the background can dramatically decrease battery life.
