Vracer has 2 main modes of operation:
1. Session Recording
While driving, using your mobile phone or tablet in your race car, Vracer uses GPS data to provide
2. Session Review
Easy comparison between your laps, and your friends or fellow racers.
Review yourself after your session, or Pit Crew can review while you're still driving (requires data connection)
Vracer can work with either:
(a) your phone's built-in GPS receiver, or
(b) an external GPS receiver, connected wirelessly to your phone via Bluetooth
Phone GPS receivers are usually 1 sample per second, compared to 10 for an average external receiver, or 25 samples per second for a modern receiver.
Yes! We'd love to be your remote driver coach!*
We've done this with many drivers and have always found between tenths and entire seconds to gain on the track.
We do this by comparing against other public driver data + sessions, or between the driver's own session data, if there is insufficient data from other drivers. We can typically find 2 or 3 opportunities to focus on for each session.
We can easily spot issues such as:
- early braking/'slow in'
- too fast entry - 'fast in, slow out'
- car performance/power issues
- slow gear shifts
- low apex speeds
- (with CAN data) throttle and brake application issues, oversteer/understeer
* available to Clubman, Pro and Elite packages
Compared to official transponder-based timing systems, GPS lap timing can be very accurate. Accuracy achieved depends mostly on the type of GPS receiver used, and the quality of the GPS 'lock'.
Some rough guides:
- phone GPS (1 sample per second), usually sub-0.1 sec accuracy
- 8-10Hz receiver - e.g. Garmin GLO, Qstarz, Dual XGPS160 - approx 0.01 sec accuracy
- 25Hz receiver - e.g. Racebox Mini - sub-0.005 sec accuracy
To achieve best results, we recommend that you mount your GPS receiver device with a clear view to the sky, to minimize interference that may block GPS signals.
Our recommended receiver:
The RaceBox mini, or RaceBox mini S. This provides 25 samples per second for best-in-class lap time accuracy at a great price. It's performance meets or exceeds that of professional GPS race timers costing up to several thousand dollars.

Can't find it - contact us to create one, or you can create your own custom CAN profiles in the app.
When running Vracer in your vehicle, it transmits frequent data to the cloud (requires data connection, e.g. 4G/5G cellular or Starlink).
Any data that Vracer is collecting can be transmitted, including:
You can view the data on a regular browser (works best on a windows/macOS device) via the Vracer telemetry portal, https://dash.vracer.io (requires login)
Account creation can be initiated from inside the Vracer app, via the settings menu, see video guide here
Yes! You can easily import data from other apps to Vracer. We current support the following formats:
- Vbox/.vbo - TrackAddict and Vbox products
- Rcz/.rcz - Racechrono and Racechrono Pro - single session and multi-session formats supported (we recommend the multi-session method if migrating all data from Racechrono)
- NMEA format
See video guides for how to perform data import. Please contact us if you'd like to import from other formats.
For Android, you can download it from the Google Play app store here
For iPhone/iOS devices, we're still working on this, see above
Location
We recommend you mount the phone within arms reach, and oriented so the screen is clearly visible to the driver.
Note that most phone touchscreens don't work through racing gloves! There are 2 solutions to this:
1. buy a set of these touchscreen-friendly racing gloves, or
2. remember to start Vracer recording before you put on your gloves!
Mounting Method
This is a very serious matter. A loose phone in your vehicle cockpit may become anything from a dangerous distraction to a lethal projectile. For this reason, many motorsports governing bodies are now mandating against suction cup mounting solutions.
We have used and highly recommend the RAM Quick-Grip models, with a sturdy screw-down or roll cage mount.
Always be sure to contact your local track or club to find out your local rules around mounting of anything in your car whilst on track, including phones, cameras, and other items.
To compare the best lap from 2 sessions
- select both sessions using the checkbox in the top left of the session image, then select 'compare'.
This will start a virtual 'ghost car' video replay of the laps, showing the time and distance gap between the cars throughout the lap, drawn on a map of the track.
In addition to the car positions on the map, GPS data traces are shown below.
