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. 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. Optionally, you may input the Finish Line GPS coordinates. For your convenience, four preset Finish Line coordinates are included for both the Northbound and Southbound segments of Big Bend and Silver State Classic courses, but verify these coordinates with the race organizer. If you chose the Finish Line coordinates option in the Setup, then the Time Error to the Finish Line is computed when you are within one-half mile of the Finish Line. 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. Also, you may record time and distance covered and 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. For better GPS reception and improved accuracy, third-party wireless GPS receivers are recommended. This app has been tested with Bluetooth connectivity to a Dual XGPS150A GPS Receiver. This app works with both iPhones and iPads, even those without Cellular connectivity. However, there can only be one Apple device with Bluetooth activated within range of the Dual Receiver. Place devices not running this app in Airplane mode and be sure that the Dual Receiver is connected with the device and app you are using. Disclaimer: Continued use of GPS running in the background can dramatically decrease battery life.
N.S.A.T.
This application assists in achieving a time closest to a target average speed for race courses. It uses a specific GPS device to automatically start and stop timing, storing results in a log. Users can configure existing courses or add their own for practice.
- Target average speed timing
- Automatic start/stop with RaceBox GPS
- Course configuration and saving
- Results log file

Neal's Sorta Accurate Timer (NSAT) is an application designed to help assist with attaining a time closest to the "perfect" time based on a target average speed over a predetermined rally race course. This is accomplished by utilizing a RaceBox GPS device to automatically start the timing based on a preselected time. The course name, distance and finish longitude / latitude are configured and saved in advance. The timer will automatically stop when the finish latitude and longitude are reached. Results of each rally course are stored in a log file. Typical events where this application is used include: Silver State Classic Challenge, NORC, Big Bend Open Road Rally and similar rallies. The app includes preconfigured courses for Nevada and Texas events, but you should always confirm finish line latitude and longitude since race officials may change these without notice. This app also supports "red flag restarts" for the Nevada events. You can also edit courses or even add your own courses for practice at legal speeds. Please note that this app REQUIRES the use of a RaceBox Mini device and is not designed to work with GPS from any other manufacturers. I am not affiliated with RaceBox, but chose their device because it is my personal preference. Understand that this is a FREE app and may not be perfect. I built this app as a way to give back to the open road race community that I love and to provide a reasonably simple solution for those who would like to try GPS timing. Now, just have fun and be safe.

Verdict
The clearest difference is review sentiment: N.S.A.T. at 100% against Open Road Race Timer's 33%. N.S.A.T. also leads on price (Free vs $14.99) and rating (5.0 vs 2.7). Open Road Race Timer's advantage is chart position (#195 vs unranked) and ratings volume (13 vs 2). On ads, in-app purchases and device support there is nothing between them.
