MU:note is an iPhone and Android app that listens for the instrument you set and automatically records only the time you actually play.
iOS & Android app · works without an account
MU:note listens and keeps only the time you actually played.
Press start, practice — the app does the rest.
Built for music majors and students who are in the practice room every day.
Put your phone nearby and start practicing. Forget about the timer.
Time adds up only while the instrument you set is heard. Other instruments and noise don't count.
Your true playing time and focus build up on the calendar. Lock the screen and the timer and detection state stay on your Lock Screen. On days you practice 20 minutes or more, a two-sentence note arrives.
Connect with a friend code and their Mucho walks into your practice room. Friends who practiced today play; after a few days off they lie down. Send clap, fire, and note reactions to today’s cards.
You choose what friends see. Piece names and notes are never shown to friends.
A tool for the practice room, every day — so each part is kept quiet and simple.
MU:note recognizes the instrument you set — and nothing else. Turning pages, sipping water, short breaks: none of it is counted. Any silence longer than 15 seconds is left out. Piano, strings, winds, voice, and guitar (acoustic and classical) are supported.
Sound is analyzed on your device and discarded instantly. No audio file is created. Nothing is sent anywhere. MU:note doesn't listen to what you play — only whether you're playing.
After each session, pick the pieces and practice types, and jot a quick note. The calendar shows every practice day, with daily totals and focus.
On days you practice 20 minutes or more, you get a two-sentence note drawn from your history. It uses numbers only — practice time and focus. Your notes and piece names are never sent.
Records and the calendar work fully without signing up. Sign in, and your history is stored safely — switch phones or reinstall, and it comes back.
One gentle reminder a day, at the time you choose. It never scolds you for a day off. Off by default.
Write down today’s goals and tick them off. Set a D-day for an audition or competition, and leave a short note for the day.
Research-checked guides written by a music educator.
Piano, strings, winds, voice, and guitar (acoustic and classical). Each instrument sounds different, so detection is tuned to the one you choose in settings.
A practice timer keeps running from start to stop, through page turns and breaks. With MU:note you press start once, and it counts only the time you are actually playing. Silences longer than 15 seconds are left out.
Yes, acoustic and classical guitar. Choose guitar in settings so detection is tuned to it.
No. Sound is analyzed on your device and discarded instantly. No audio file is created, and nothing is sent anywhere.
No. Records and the calendar work fully without signing up. Sign in, and your history is stored safely — switch phones or reinstall, and it comes back.
No. Turning pages, sipping water, short breaks: none of it is counted. Any silence longer than 15 seconds is left out.
Your name and main instrument are always visible. Whether you practiced today, practice time, streak, days this week, focus, and whether you’re practicing now are shown only if you turn each one on. Piece names and notes are never shown. You can block and report.
Friends is for signed-in members only. Records and the calendar still work without an account.
Yes. You can get it on Google Play. Friends on iPhone and Android stay connected, and if you log in with the same account, your records come with you when you switch phones.
MU:note is made by munote, founded by Jisoo Kim, a music educator with a master's degree in music.
The time MU:note counts is the time we practiced together.
Practice done without the app is still practice.
