ST1 Track Day

Hey Product Hunt 👋 I’m Mario, a racing fan from Switzerland 🇨🇭 I grew up with Gran Turismo and Need for Speed, and one day I thought — why not build my own lap timer app? No investors, no plan, just passion and a bit of obsession 😅 ST1 Track lets you record your laps in real time, automatically detect lines, and even create your own circuits directly from your GPS. Everything runs on your phone — no sensors, no subscriptions, no nonsense. The app is 100% free, community-driven, and made for people who simply love driving. I’d love to hear your thoughts, feedback, and ideas for the next updates! Thanks for checking it out 🏁
