GPS Ride Tracker is a very simple application for keeping tracks of your rides (on foot, bicycle, car ...). Press Start and it will memorize all GPS points calculated by your iPhone. You can also store points of interest.
It is very easy to recover the data saved by this application: just ask it to send you an email with the data file attached, in Google Earth kml format.
When you receive the email, start Google Earth on your computer, and open the KML file: Your ride will appear on the map.
You can keep as many ride GPS log files as you want.
For your privacy, we use Mail application for sending the email. So, we never see your GPS location. It is also very usefull when sending email when you're not connected to internet. They will stay in the Outbox until your iPhone is connected to internet.
