# Tempo Kit

> Tempo Kit is a Chromium-based browser extension for musicians. It puts a metronome, chromatic tuner, timer, stopwatch, practice library, notes, and video practice controls in one browser side panel.

Tempo Kit is built for musicians who practice with browser-based lessons, videos, tabs, and local audio or video files. The extension is designed to reduce app switching during practice by keeping core tools and video controls beside the page the musician is using.
