Most sim racing tools are heavy apps (.exe) that drain FPS. ApexState is different. 🚀 Zero-Install Web App: Runs in your browser on a second monitor, iPad, or phone. No install needed. 🧮 Physics Engine: Uses Python to calculate "Braking Migration," predicting exactly how many meters earlier to brake as tires degrade and fuel burns off. 📝 Engineer's Notebook: Save strategy notes (e.g., "Shift early") directly to the track map. Notes save locally to your browser—no login required.
