Real race engineering, for the rest of us.

Every F1 driver has a race engineer. We think every sim racer deserves one too.

Why we built it

Watching an F1 race, the engineer on the radio changes the outcome more often than the driver. "Box, box, box", "let him through", "mode overtake, five laps" — small calls that win races. Sim racers make all of those calls alone. Apex Engineer puts a real engineer in your ear.

Engineered for performance

Most sim-racing tools are Electron apps that steal 500MB of RAM and a few FPS. Apex Engineer is built on Tauri — a Rust core and a minimal WebView front-end. You run it and forget it is there.

Built by racers

We have spent thousands of hours on F1 25, iRacing, and ACC. We know what a good engineer call sounds like — and we know what a bad one does to your lap.
