S1napse

The story

I'm a sim racer, and I wanted a better way to understand my own laps. Every telemetry tool I tried had a catch: it was locked behind a subscription, it only worked with one game, or it was too cluttered to read while driving. None of them worked with real cars either.

So I built my own. S1napse is a desktop app that reads live data from five racing sims, including ACC, iRacing, and Le Mans Ultimate, and from real cars through an OBD-II adapter. After each session, it breaks down every corner and gives coaching tips, analyzes tyre wear and strategy, and builds a track map from the laps you drive. I built the whole thing myself, from the code that reads each game's data to the interface and the Windows installer. It's free and still in active development, and the people using it are sim racers like me.
