StintFlow helps Le Mans Ultimate racers keep track of their sessions and plan their races. It runs on your desktop and provides:
- automatic logging of stints while you drive
- strategy tables to plan and compare how to approach the race, both before and during an event
- real‑time integration with the LMU game so you can see live data on your screen
- a history of past races stored on your computer for review and analysis
If you're a regular user or player and just want to try the software, head to the Releases page and download the latest build for Windows. No programming knowledge is required – just unzip and run the StintFlow executable.

cd StintFlow
python -m pip install --upgrade pip
