Open Road Race Timer


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.


Speeds can be set at 5 mph increments from 80 to 160 miles per hour. Typically, offroad races run one way over the closed course and then teams turn around and reverse the course for another run. In this app, you can set the distance between 40.00 and 120.00 miles for a single run.


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 and 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.


You may override the countdown to an automatic start by touching the "Start Now!" button. However, be aware that if the race is timed by a clock to which you have synchronized the app's clock, it may be unwise to start by manually touching the button.


An adjustment factor between 0.800 and 1.200 can be used to synchronize distance measured by GPS to race distance. This adjustment applies to all distance measurements shown after the adjustment has been selected so adjustments can be made while racing.


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


For better GPS reception and improved accuracy while racing, third-party wireless GPS receivers are recommended. This app has been tested with Bluetooth connectivity to a Dual XGPS150A Universal GPS Receiver, which samples at least five times per second. The Dual XGPS160 model samples at least ten times per second for even greater precision.


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


       



changes in version 5.0
  • Changed minimum required iOS version to 10.3 to resolve some issues and to accommodate new technology
  • Reduced from 10 meters to 1.5 meters (33 feet to 5 feet) the minimum distance computed from a pair of GPS coordinates suitable for incrementing distance. This improves displayed distance measurement to 0.001 mile accuracy, which is especially important at speeds less than 15 mph (not much of an issue at the speeds required of this app)
  • Various changes to accommodate iOS 11
changes in version 4.0
  • Added estimate of distance travelled between GPS distance signals. This improves the accuracy of the distance measurement and importantly reduces the rapid changes in time and distance error computations and displays to make it easier to maintain a desired pace
  • Added app Settings to change the display of time, speed, and distance
changes in version 3.0
  • Substantial redesign of the GUI for better readability and to display more prominently key indicators of race progress. In particular, errors in time and distance at the set speed are displayed on to the right and left of the average speed, now showing in the center of the screen just below the title
  • The Driver's display now shows the errors time, speed, and distance as well as the time remaining to complete the course
  • A "Start Now!" button has now been added to allow you to override the automatic starting time. However, use this button with caution, because the finger touch may not be as precise as an automatic starting time if the app's internal clock has been correctly synchronized with the official race clock
  • Various code improvements and tweaks
changes in version 2.4
  • Added option to adjust Time of Day (T.O.D.) clock to match official rally clock, if necessary
  • Adjustments, if any, to odometer or time are shown in the right-hand corner of the lower toolbar
  • Table of splits is wider and has a larger font for better readability
changes in version 2.3
  • Change the minimum distance to 10 miles and the maximum speed to 160 mph in response to customer suggestions
  • Some GUI changes to better accommodate different iPhone models and iOS 10
