Find the tenths you're missing.
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 slices the lap into segments and shows where you give up time — versus your best lap and versus a rival. Stop guessing: see the corner, the braking point, the tenth.
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. The neural voice is optional and runs without internet.
“Sainz 0.8 ahead — DRS next lap.”
“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.
Study all 22 rivals
Pacedex records every car's strategy and driving: stints, pit stops, pace by compound, and their racing line vs. yours. Show up to your league race already knowing the opposition's game.
