You control when the listening begins. 🔎 Made for browser music This tool is useful when you want to count BPM song tempo while listening in Chrome or another Chromium-based browser. It is not built around file uploads, audio editing or complex production tools. It works well for quick checks: a DJ checking a track speed a musician comparing rhythm a dancer preparing a reference a video creator choosing music pace a teacher explaining beats per minute a listener trying to understand song BPM The side panel format keeps the extension close to the page, but separate from the website interface. 🎚️ Clean tempo detection Some tools are built for manual rhythm input.
