Quick BPM Finder estimates tempo from an audio file, microphone input, or manual taps. Processing stays in your browser, so audio is not uploaded. It works without an account and lets you copy the estimated BPM in one click. Results are estimates and may settle on half-time or double-time when a beat is ambiguous.
Hi Product Hunt — I built Quick BPM Finder for anyone who wants a fast BPM estimate without uploading audio or creating an account. You can analyze a local audio file, use the microphone, or tap along to the beat. The tool runs entirely in the browser and clearly explains where tempo detection can be uncertain, including half-time and double-time results. I’d love feedback on the mobile flow and the clarity of the result.
