1. Also, you may adjust the location coordinate by the distance between the GPS receiver in the car (either the iPhone or iPad or some third-party GPS receiver) and the position on the car where a rally may measure time or location at timed controls (sometimes this is the front of the car or the center of the front wheels).

2. This app is designed for various types of automobile rallies that require measurement of time, speed, or distance between segments of the rally route including stages and checkpoints.

3. To fine-tune the app's distance between GPS receiver and front wheels (if necessary) and clock time figures to the rally's official measures with the options in the Adjustments popup.

4. Begin computing distance, time, and speed by touching the "Start Rally" button.

5. A log view shows additional information at each stage including the latitude, longitude, and the current speed at the time the New Stage button was touched.

6. If the app's Time of Day (T.O.D.) clock does not match the rally's official clock, you may synchronize the two clocks by making small adjustments as required.

7. From time to time you may measure time, speed, and distance for a stage or a checkpoint.

8. Distance measurement can be set to miles or kilometers and time measurement can be set to minutes and seconds or decimal minutes.

9. The app is designed to adjust the GPS coordinates of a moving vehicle owing to the time between reception of new GPS signals and to the time lag between the time the signal was generated from satellites and the time when processing actually occurs in the app.

10. You may pause or gain time on a particular stage by adding or subtracting time from the reported time on a stage.

11. These three potential errors in coordinate measurement are discussed at length in a 6-part thread in the Facebook "Road Rally Tech Talk" forum.
