My Tracks for Android

My Tracks records your path, speed, distance, and elevation while you walk, run, bike, or do anything else outdoors. While recording, you can view your data live, annotate your path, and hear periodic voice announcements of your progress.

With My Tracks, you can share your GPS tracks and stats online:

Via Google+, Facebook, or Twitter
Using Google Maps, Google Fusion Tables, or Google Docs
As a GPX, KML, CSV, or TCX file
My Tracks uses the GPS sensor in your device to record geographic and velocity statistics, but the app also syncs with third-party biometric sensors, including:

Zephyr HxM Bluetooth heart rate monitor
Polar WearLink Bluetooth heart rate monitor
ANT+ heart rate and speed distance monitors (these require an ANT+ compatible phone)
