Odometer+ "works"

I have just got into biking again at 65. My wife and I wanted to keep track of our distances and our bike rides. Down loaded this and tried it on the open road with my car odometer first. It was a bit jumpy when we first turned it on, we went 3 to 4 hundredths of a mile before we moved the car. After restart it stayed very close to the cars odometer as we drove to the route we normally bike. then we tested it on our route and it stayed with in .01 or .02 of mile with my car.
I would like it if I could clear some of the old tests from the record.
But for now I feel it was worth the 99¢.
