Tracks Pro 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 supported Ant and Polar heart rate monitor, you can also see your continuous heart rate.
Your Tracks data is stored on your phone. You control whether you want to share with others.
With 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. In addition to Google Drive, you can also export your tracks to Google My Maps, Google Spreadsheets, or external storage.
Tracks also supports Android Wear. For watches with GPS, Tracks Pro can perform GPS recording of tracks without a phone and sync tracks to the phone. For watches without GPS, you can see your current distance and time, and control the recording of your tracks from your wrist.
You also see I published "Tracks" app. I lost an important publish key so I am not able to update that app, and I have to publish new one.
The difference between the two apps:
1. Tracks Pro support syncing with Google Drive.
2. Tracks Pro let you donate to cover some costs related to this app, such as using Google Map service.
