このツールについて

Online Metronome is a free, browser-based tool that lets you play with music tools instantly — without installing software, signing up, or uploading files to any server. Everything happens locally in your browser, so your data stays on your device.

This tool is built for everyday use: from quick one-off tasks to repeated workflows. It loads in milliseconds, works offline once cached, and runs equally well on desktop, tablet, and mobile. The interface is deliberately minimal so you can focus on the result rather than learning the tool.

Common use cases include: practicing with a metronome or tuning your instrument; working out chord progressions for a new song; learning music theory hands-on; quick reference during a session. Whether you're a student, a professional, or just need a quick utility, Online Metronome gets the job done in seconds.

Privacy is built in by design. Because all processing happens client-side in your browser, no analytics service, advertising network, or backend ever sees your input or output. You can verify this by checking your browser's network tab while using the tool — you'll see zero outbound requests for your data. That makes Online Metronome suitable for sensitive content (medical, legal, financial) where uploading to a third-party service would be a non-starter.

Online Metronome is part of ToolHub — a free, ad-free, open-access collection of 750+ in-browser utilities covering PDFs, images, text, calculators, developer tools, design, social media, education, business, health, and more.
