PaceWhere every thousandth counts.
Live overlay, a voice race engineer, and corner-by-corner analysis. Pacedex shows you exactly where you lose time — and helps you get it back, lap after lap.
Built on track, side by side with a pro virtual F1 driver — not in an office.
Everything you need to fight for tenths
Where you lose time
After the race, Pacedex compares your lap metre by metre — against your best and against a rival — and shows exactly where you give up time. Speed, throttle and braking overlaid: see the corner, the braking point, the tenth.
The fix, read from your telemetry
Understeering into a corner? Rears locking under braking? Pacedex reads your telemetry, names the symptom and points to the setup change that tends to fix it — so you stop guessing in the garage.
Nail your setup, click by click
The game won't let you import a setup. So Pacedex puts your target setup side by side with your garage, live: each field turns green when it matches, with an arrow to go up or down. Clone the ideal setup — from a per-track reference base.
A race engineer in your ear
Real-time callouts, offline: tyres on the limit, fuel, undercut window, rain incoming, “box, box”, car on your left/right. It learns each track's tyre wear to call your pit window — and you choose which calls you hear, by category. The realistic voice is optional and needs no internet.
“Sainz 0.8 ahead — deploy overtake.”
“Tyres are done. Box, box.”
“Car on your right.”
Live overlay on top of the game
HUD, timing tower, minimap, battle (ahead/behind) and grip — always-on-top windows, broadcast style. Each one moves, resizes and toggles by hotkey, without leaving the game.
The traction circle, live
How much the car still has to give — in real time. The circle plots lateral and longitudinal G in a single dot: how close to the limit you are in every corner and braking zone, and whether you're understeering or oversteering.
The car ahead and behind, live
The gap to the car in front and the one behind, updated every lap — plus each one's tyre. See at a glance whether you're pulling away or closing in, and if your rival is on a softer compound. Know when to attack and when to hold.
Study 22 rivals — then export
Pacedex records every car's strategy and driving: stints, pit stops, pace by compound and their line vs. yours. After the flag, see the full classification and export it to CSV for your league — show up already knowing the opposition.

Frequently asked questions
Is it free?
Yes — the beta is free. Cloud and community features come later.
Is it hard to set up?
No. A quick installer, then switch on UDP Telemetry in the game — you're racing in a couple of minutes.
Does it work offline? Does my data go anywhere?
Your racing/telemetry data stays on your PC — it's never uploaded. The app only makes an anonymous check for new versions (a random ID + version, no personal or race data), which you can turn off. The realistic voice is downloaded once (optional).
Which game is supported?
EA/Codemasters F1 (F1 24, 25 and 26) on PC, via the game's official UDP telemetry output.
Is it allowed?
Yes. We use the telemetry output the game itself provides — built exactly for apps like this.
