Hey Product Hunt! 👋 Free chess clock apps are often ad-cluttered or app-store-only. So, I built Chess Clock Online — a browser-based timer, zero sign-up, zero ads. FIDE-standard Bullet/Blitz/Rapid presets, Fischer/Bronstein/simple delay modes, FIDE multi-stage controls, and a Face-to-Face mode that flips the screen 180° for two players sharing one device. Works offline once loaded. Try it for your next OTB game — feedback welcome!
