The Open Road Race Timer is designed for high speed automobile racing on closed highways. The race objective is to travel a course of known length at a set rate of speed. That combination of speed and distance translates into a target time to reach the finish line.

There are separate screens for the Navigator where conditions can be set and for the Driver where progress measured against the ideal time can be presented for a heads-up display.

Your starting time will also be assigned as some minute or half minute after the hour in which the race begins. Set the conditions of speed, distance and compute the time in the app Setup and let the app count down to the start of your race.

If the computed time is not identical to the official time down to the ten thousandths of a second, touch the "Distance" button to activate the plus and minus below the time to make fine adjustments. Time is the most critical variable for displays and computations.

The clock will countdown to an automatic start. If possible, synchronize your app's clock to the offical race clock before you start.

Alternatively, you may show a Start Now button on the main screen by chosing the option on a switch in Settings and use this button to initiate the start. Caution, however, the automatic countdown timed start is much more precise and reliable than any human could possibly be.

Speeds can be set at 5 mph increments from 60 to 170 miles per hour. Shorter distances and slower speeds can be used for practice.

Settings allow you to change the precison of various displays. Also, there is a setting that determines whether the app stops computing at the Finish Line based upon either the official time or the official distance. By default, the choice is to stop app computations when the distance to the official finish line reaches zero. Then, you will have an indication of how much time error you have incurred on the course.

Optionally, you may input the Finish Line GPS coordinates if those are known or provided by the race organizer. For your convenience, Finish Line coordinates are included as options for both the Northbound and Southbound segments of the Big Bend and Silver State Classic courses, but be sure to verify these coordinates with the race organizer.

If you chose the Finish Line coordinates option in the Setup, then the computated Time Error to the Finish Line is computed when you are within one mile of the Finish Line GPS coordinates.

For races with out and back stages where the total error is the average between two runs, you can use this time to judge the best time target +/– on the return stage.

GPS inputs trace the path along the rally route. Measurements of actual versus ideal time and distance will be shown in seconds ahead or behind schedule. From time to time you may also record time and distance covered an the error against the ideal course time and distance by touching the Add Split button. Also, you may set automatic split computations at increments of 30 seconds, 1 minute, 3 minutes and 5 minutes.

You may 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. Unlock to make adjustments and lock to save the changes you make and to prevent inadvertent changes.

If the app's Time of Day (T.O.D.) clock shown at the bottom of the map view (or in the center of the display in the iPad version) does not match the rally's official clock, you may synchronize the two clocks by making small adjustments as required.

App Settings allow you to change the display of Time, Speed, and Distance as well as permitting the display of Time error to be in whole numbers or decimals.

Disclaimer: Continued use of GPS running in the background can dramatically decrease battery life.

What’s New

Version 7.3

- 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.

Glitches on every leg. Race-ruining bugs.

Competed in the Bug Bend Open Road Race intending to use this as our primary timing device with stopwatch backup. Glitches on both practice runs that stop displaying timing information almost two miles from the finish line (at approximately 57 miles down the course, the timing went haywire and started showing huge and rapidly varying numbers). After assuming it was related to not starting the app directly on the official start line during practice, we ran it in the first leg of the race. Same problem, lost all timing info miles out from the finish line. Changed settings to use total time instead of total distance for the return leg, and the time started gaining entire seconds about 1/3 of the way into the race. Had to revert to stopwatches for the remainder. Everyone else we talked to that used it had the same issues. Worthless app with the current bugs.

Horrible is an Understatement

Not even close to be accurate or actually functional for trying to use in a real open road race. Tested a minimum of 7 trips with 3 phones in the vehicle, same start and ends points each trip - from totally nonfunctional to not even in ball park on being accurate.
50% of the time on one or more phones, the app never found the finish and continued to run!
We used numerous methods to try and make this.
P.O.S - do not use. The only valuable function is the start method, other than that it’s worthless.

Awesome road race app

I love this app. I just wish I had the millisecond update 2 weeks ago :)
