With My Tracks, you can sync and share your tracks via Google Drive. For sharing, you can share tracks with friends, see the tracks your friends have shared with you, or make tracks public and share their URLs via Google+, Facebook, Twitter, etc. Hopefully the following is a direct link to the app on the Play Store My Tracks
In addition to Google Drive, you can also export your tracks to Google Maps, Google Fusion Tables, Google Spreadsheets, or external storage.
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)
