A simple online interval timer for HIIT

I’m a front-end developer specializing in React and Next.js. I love creating small apps that help others. IntervalTimer.fun is a minimal online interval timer for HIIT workouts. It works as a PWA, supports offline usage, and has a picture-in-picture mode (only on compatible browsers like Chrome-based ones). No login, no tracking—just set your intervals and start your session. Feedback is welcome!
