Ping is an app to send location data to Trackleaders.com for display on live event (race) maps. It is used to track bike rides, ultra-runs and other long distance competitive events.
Its a very simple app that is meant to supplement satellite based tracking data (SPOT/InReach) or replace it for events that have good cell coverage.
A very clear on/off switch controls whether tracking is active.
It is free to download and use. No ads, no extras, just a simple and effective app.
