- Fixed bug that sometimes causes average mph display to produce odd results.

- Major update to the Dual SDK version 2.2 that permits more effective data validation and Bluetooth connectivity. Thus, this app can now be used with iPads that do not have Cellular capability. Remember to put other iOS devices in Airplane mode, while using this app on iPad.
- Fixed bug involving display of user-defined finish line coordinates.
- When using preset or user-defined finish line coordinates, the app will compute distance to the finish line that, in turn, is used to compute time error to the finish, plus or minus, within 0.5 miles of the finish line rather that 1.0 miles in previous versions.
- Notable improvements in processing valid GPS data derived from Apple and Dual.
- Minor GUI changes.
7.3.1

- Minor changes to accommodate iOS 13 and 14.

- The major code improvements and additions are 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.
- Users may now 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).
- All three of these potential errors in coordinate measurement are discussed at length in a 6-part thread in the Facebook "Road Rally Tech Talk" forum.
- If available to the app, compass coordinates are available to verify location when the car is stopped.
- Various improvements to the processing of information from the Dual 150 and 160 GPS Receivers.
- Changes to processing of Apple internal GPS signals to account for spurious readings when horizontal accuracy is poor or when the vehicle is stopped or moving very slowly.
- Various changes and improvements in the GUI to improve display and readability.

- GUI changes necessitated by iOS 13.

- ESSENTIAL REQUIRED UPDATE. Fixed bug in this version 7.01. The longitude of the Southbound finish line of Silver State should have been -115.219650.

- To improve the accuracy of Time Error as you approach the Finish Line, there is now an option in the Setup that allows you to insert and use the GPS latitude and longitude coordinates of the Finish Line. Be sure to use the Official GPS coordinates provided by the race organizer and insert the coordinates to six-digit decimal precision when possible.
- If this option is chosen, Time Error computations will use the GPS distance to the Finish Line once you are within one mile of the Finish Line GPS coordinates.
- Additionally, the current official Finish Line GPS coordinates for both the Northbound and Southbound legs of the Big Bend and Silver State Classic races are provided as options. Choose user-defined coordinates or preset coordinates by turning on the slider button to the right of the option display. Turning off all the slider buttons will ignore the coordinate options, while turning any one on will indicate that you have made the choice in the Setup display and on the main display at the bottom of the Splits table.
- Various GUI tweaks and enhancements.

- A new Settings option has been added. This option gives you the choice of stopping the app computations when the distance between the car and the finish line reaches zero as determined by the GPS distance traveled over the course or when the time on the course counts down from the official time to zero.
- The default Setting is for the app to stop when the distance traveled counts down to zero, which should be when the car crosses the official finish line.
- This option is designed to help teams adjust time targets for the second leg of an out-and-back race like the Big Bend ORR. The total time error for this two-stage race is the average time of the out and back stages.
- There is now a display of the distance "to go" until the finish line shown above the map display.
- Improvements have been made to allow selected time, speed, and distances in the Setup screen to persist in the app Documents folder.
- Minor GUI enhancements and code improvements to improve performance.

- Top speed has been increased from 160 mph to 170 mph
6.2
2016-05-01
- Location Services must be turned on to use the app regardless of whether the GPS signal comes from Apple's internal receiver or a third-party receiver like the Dual 150 or Dual 160. Also, Bluetooth must be turned on to use the Dual GPS receivers.
- So, to remind you that the GPS signals must be gathered, processed, and settled down before leaving the starting line, the app now defaults to showing the GPS information view superimposed over the map.
- Several GUI changes/improvements to both the main view and the Driver's popup view, most notably the addition of up and down arrows where red indicates that you are ahead of the target pace and green indicates that you are behind the target pace and should speed up.
- Settings of Time, Speed, and Distance will persist after having been set, but notice that the starting time does not persist. So, if you go back and forth between the setup view and the main view, the time to start may change. Be careful to set the correct starting time.
