Tempokit — Metronome, Tuner & Practice Studio

About

Tempokit is a complete music practice studio in one private browser tab — a metronome, a
chromatic tuner, a reference drone and a practice log — with no ads, no account and no cloud.

METRONOME
• Steady Web-Audio timing with tap tempo and a tempo slider (30–300 BPM)
• Any time signature — 4/4, 3/4, 5/4, 6/8, 7/8, 9/8, 12/8 and custom
• Subdivisions (eighths, triplets, sixteenths) and click-to-set per-beat accents
• Count-in, a visual beat, and an auto "tempo trainer" that speeds you up as you nail each pass
• Save one-tap setlists for your songs and exercises
• Lives in the side panel so it keeps time while you watch a lesson in the main tab

TUNER
• Chromatic microphone tuner showing note, cents and frequency
• One-tap reference tunings for guitar, drop D, bass, ukulele, violin and cello
• Adjustable concert pitch (A4 415–466 Hz; 432 / 440 / 442 / 444 presets)
• Audio is analysed on your device only — never recorded or sent anywhere

DRONE, PRACTICE LOG & REFERENCE
• Sustain any pitch (with optional fifth/octave) for intonation practice
• Session timer + practice journal with day streaks and a 14-day chart
• Scale explorer and instrument tuning reference

PRIVATE BY DESIGN
• 100% local — nothing leaves your browser
• Only two permissions: storage and side panel. No host permissions, no tracking, no ads.
• Works fully offline. Export/import a backup whenever you like.
