WHAT IS RALLYMETER? The definitive system for regularity competitions. There is none like it. Historical regularity, Sport regularity, Raids, Moto … We never abandon our users, the app is ALWAYS updated with improvements and developments (some improvements may be paid but updates are always free). Ready to be used with our “blackBox” system or with an external precision GPS receiver (Gramin GLO). Continued support for the app through our website, facebook, twitter, youtube … Rallymeter allows you to: Enter times and link distances to be able to arrive on time at the start of the next section. Program the route card and you will have the calculation of the starting times in one click. Add as many averages as you need (up to 999). Roadbook references with or without photo to facilitate navigation and / or adjust step distance with one click. The simplest calibration system on the market. Average changes by reference (milestones). Table mode to predict passage times for imposed distances. With the possibility of manually varying the prediction distance during the section. Mix average changes with average changes by reference or imposed time sectors (tables). Pyramid mode “on the fly” that allows you to start without programming a section and make the average changes manually in case they give us the information of the section just when starting, without time to program it. Possibility of “freezing” the measurement to check references. Partial distance counter. Manual distance adjustment at any time. Use of up to four calibrations for different types of section with indication of meters added or subtracted from the initial calibration per km. SPORT REGULARITY Maximum precision. Adjustments to the tenth. Difficult, fast, demanding and above all precise. This is how regularity sport rallies are. Their special characteristics require special systems and methodology if you want to be at the top. Rallymeter has no rival when it comes to defining and exploiting these peculiarities. Designed for precision but also to relieve the co-pilot of superfluous tasks when on many occasions he has to help the pilot with speed notes. RAIDS and OFF ROAD Mud, sand, impossible tracks and many obstacles define regularity raids. Special and peculiar, enough for the measurement system to be too. Rallymeter has adapted to the use of external satellite receivers (compatible with iOS) such as the Garmin GLO to improve the coverage and insufficient refresh rate of phones and tablets. Up to ten readings per second and a precision radius of five meters mean that off-track distances have never been so accurate.

This application precisely tracks time, speed, and distance for automobile rallies. It allows for detailed segment measurements, on-map plotting, and real-time adjustments for off-course travel or GPS inaccuracies.

Highlights
  • Time, speed, and distance tracking
  • Stage and checkpoint measurements
  • On-map plotting of rally path
  • Adjustable distance units (miles/km)
  • Off-course distance subtraction
  • GPS coordinate adjustment
  • Time adjustments for stages

Read full description

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. To make sure that all initial conditions are set properly when using GPS, touch the "Reset/Pause" button and choose the "Reset, New Rally" option. Also, it is important to allow Apple's internal GPS time to determine the current location and to begin interacting with the app by driving around a bit before you start using the app on a rally course. Begin computing distance, time, and speed by touching the "Start Rally" button. Alternatively, when the app has been either restarted to zero distance or paused, you may select a minute for the "Next Starting Time." GPS inputs trace the path along the rally route. From time to time you may measure time, speed, and distance for a stage or a checkpoint. These measurements will be stored in a table and the points will be indicated on a map. An alternative view showing the odometer measurements more prominently is available by touching the "Mode" button in the upper menu bar. You may subtract distance when you travel off course. A toggle button switches between on course (blue line) and off course (red line) travel. Distance measurement can be set to miles or kilometers and time measurement can be set to minutes and seconds or decimal minutes. The distance may be displayed with either 2 or 3 digit precision. Make your selections by touching the Settings with a "sprocket" button beside the "About" button. 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. 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). These three potential errors in coordinate measurement are discussed at length in a 6-part thread in the Facebook "Road Rally Tech Talk" forum. 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. Unlock to make adjustments and lock to save the changes you make and to prevent inadvertent changes. You may pause or gain time on a particular stage by adding or subtracting time on a stage. Also, you might wish to "bump" the recorded GPS distance +/- to align with official rally distances. Touch the button in the lower right-hand corner to access the "bump" function. 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. Disclaimer: Continued use of GPS running in the background can dramatically decrease battery life.
