How MiRally Timing Works?
The system records the participants coordinates during the rally course
and helps the organizer to calculate the advance or delay of the competitor at each control point.
Uses GPS of participants' cell phones to capture coordinates and
the internet to send them to our servers.
A mobile phone with Android or iOS (Apple) operating system, GPS and internet access.
We recommend using modern cell phones like iPhone 4S or higher and branded Androids from 2014.
How to participate in a rally with MiRally timing?
- Register on MiRally:
- Sign up for the rally on the website calendar
- Register on site
- Register Pilot, Navigator and Vehicle
- Install MiRally Crono app:
- Find and install the MiRally Crono app on the App Store (Android or Apple)
- Sign in to the app with the email and password you registered on the MiRally website
- Check official time outside the house, where you have a GPS signal
On the event day, restart your phone to free up memory and avoid problems with the system.
Activate your phone's GPS, open the MiRally Crono app and wait for the official time to appear.
Attach the cell phone to the windscreen over the dashboard with a suction cup holder to catch a good GPS signal.
Keep the phone always connected to the charger to keep the battery always full.
Keep the application always open in the foreground.
With everything ready, do not touch the phone until the end of the rally to prevent the app from closing and stop recording.
If a red ERR message appears, notify the organizer.
- ERR(01): cell phone not registered
- ERR(02): it's not the rally day
- ERR(03): not registered or not approved in the rally
When you finish the rally restart the device to completely turn off the MiRally Crono app,
otherwise it may stays in memory consuming battery and internet data.
You can activate more than one device at the same time with the same email and password.
The system will use the best result in each of the PCs.
All GPSs have a margin of error, the more modern and higher quality the mobile is, less is the margin of error
and more accurate will be the competitor's timing.
In the MiRally Crono app we show the margin of error of your device in +/- meters.
To check the margin of error for your device, open the MiRally Crono app and wait for 2 or 3 minutes somewhere in the open.
To get the best accuracy on your GPS, we recommend purchasing a high-precision Bluetooth GPS "antenna", such as
Garmin GLO .
When connected to the phone, this device replaces the built-in GPS with a high quality signal considerably decreasing
the error in your GPS.

Huawei devices, have a low quality GPS, which does not allow to maintain the accuracy of less than 10 meters.
We do not recommend the use of Huawei devices. B>
