We were competing in RAAM, an ultracycle race from Oceanside CA to Annapolis MD. The route is broken down by distances to turn over more than 3000 miles. We had this app in all of our support vehicles. The app worked perfectly. Periodically, support vehicles needed to leave the route for supplies. With this app, we could stop and start the odometer without loss. The reality is that most vehicle odometers are inaccurate by up to 10%. This app is accurate down to a few feet. We set a new Canadian record and cane second overall in no small part to the easy use and accuracy of this app.
