A race engineer in your ear, working from a twin of the race.
Race Twin follows the whole race from your telemetry and keeps track of your fuel to the flag. When something matters, your engineer tells you over the radio, and you can ask it questions back.
Connects to your simulator
The twin works it out. Your engineer tells you.
Race Twin keeps up with every car in the race from your telemetry and works out what each moment means for you. Your engineer puts it into words on the radio, and the overlays show you the same picture over the sim.
An engineer on the radio, both ways.
Press a button on your wheel and ask a question. Your engineer answers in a natural voice, working from the live race, whether you want the gap ahead, your fuel or how your pace is holding up. It speaks up when something matters to you and keeps quiet when it doesn't. If you talk over it, it stops and listens, and if you ask it to be quiet, it will be.
- Push to talk from any wheel or button-box button, or from the keyboard.
- It knows the names in the field, so it understands who you mean.
- You decide its character in the settings.
- Every line also appears on an overlay over the sim.
Fuel to the flag, worked out every lap.
The fuel calculator keeps track of whichever runs out first, fuel or virtual energy, and recalculates as the race goes on. It tells you how much to add at each stop to reach the flag, or to run a lap or two longer, and the last lap your tank will reach. Your engineer works from the same numbers, so what you hear on the radio matches what you see.
- It follows virtual energy as well as fuel, and plans around whichever runs short first.
- Each stop comes with how much to add, whether you want to finish or go longer.
- It counts down the laps to go and knows when the leader, and you, will take the flag.
- Fuel and race clock overlays show it all over the sim.
What the twin knows, where you can see it.
Build a pit wall from widgets and give it a window of its own, on another screen above your rig. Overlays sit on top of the sim and show the radio, the race clock and your fuel. Each one also works as a browser source in OBS, so you can put it on your stream.
- Lay out the pit wall dashboard however you like.
- Choose from radio, clock and fuel overlays.
- Add any overlay to OBS as a browser source.
Track maps from your own laps.
Every clean lap you drive helps draw the track. Race Twin finds the corners from your line, and you can rename them, add new ones or remove any it got wrong. You can view the map flat in 2D, or in 3D over satellite imagery and terrain. Your engineer uses the corner names you choose.
- Corners are found automatically from your driving line.
- You can edit the name and type of every corner.
- Switch between a flat 2D map and a 3D satellite view.
- On the radio, your engineer tells you which corner things happened at.
A twin of your race
Race Twin builds a live model of the race from your telemetry. It knows where every car is, how quickly each one is lapping and when they stop, as well as the flags, the session and the track. That model is the twin. Your fuel plan is worked out from it, and your engineer speaks from it.
It learns as you drive. Your laps draw the track map, and your pace at each track is remembered for the next time you race there.
On your PC
The twin runs on your own PC, and your telemetry stays there. When your engineer speaks, all it is sent is a short written summary of the moment.
Every car
The twin follows the pace, stints and stops of the whole field, not just your own car.
Kept for next time
Your track maps, your pace at each track and every session are saved, so each race starts with what the twin already knows.
How it works
Create your account and install Race Twin
Once you have your invite, create your Race Twin account. Then install the app on your Windows PC and sign in.
Add your sim
Install the plugin for iRacing, Le Mans Ultimate or Assetto Corsa EVO from the catalogue in the app. When you start the sim, Race Twin picks up the session on its own.
Set up your engineer
Choose the button you want for push to talk, and decide what kind of character your engineer should have.
Drive
Go racing. The twin follows the session as it unfolds, the map draws itself as you lap, and your engineer is there on the radio.
Everything else under the bonnet
Natural Voice
Your engineer speaks in a natural voice and starts talking as soon as its first sentence is ready, so you aren't left waiting.
Live Event Detection
Race Twin notices flags, pit stops, offs and spins the moment they happen, along with damage, penalties and changes of position.
Session History
Every session the twin follows is kept, with each car's laps and pit stops, so you can look back on it after the flag.
Tools You Can Run
Anything your engineer can look up, you can look up yourself, including your own queries over the session's data.
Sim Plugins
Support for your sim comes from the plugin catalogue inside the app. Plugins are signed, and they update from inside the app too.
App Updates
When a new version of Race Twin is out, the app tells you and asks before it installs anything.
