Quick answers
Are all the tools really free?
Yes. No sign-up, no watermark, no caps. The maths runs in your browser, so there is nothing to meter.
Do the tools store my settings?
No. Values you enter are processed locally and never transmitted or saved after you close the tab.
Which sims are covered?
The geometry tools work for any sim. Per-game FOV entry notes currently cover iRacing, Assetto Corsa, ACC, Le Mans Ultimate, rFactor 2, Automobilista 2, F1 23–25 and GT7; we extend the list as patches change UIs.
