MU:note

Ever started a practice timer and forgot to stop it?

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.


■ Only playing time counts

MU:note recognizes the instrument you set — and nothing else.
A quick pause to turn a page stays part of the flow.
Once silence lasts 15 seconds or more, that time is left out.
When you finish, you see the time you truly played, and how focused it was.

Piano, strings, winds, and voice are supported.
Each instrument sounds different, so detection is tuned to the one you choose.


■ Audio is never recorded

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.


■ Keep a note of your day

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.


■ A word from MU:note

When a single session passes 20 minutes, a two-sentence note arrives, drawn from your history.
It's for signed-in users, and uses only stats — practice time, focus, practice types.
Your notes and piece names are never sent.


■ Start without an account

Records and the calendar work without signing up.
Past months' details and the note from MU:note open when you sign in.
Sign in, and your history is stored safely — switch phones or reinstall, and it comes back.


■ Quiet reminders

One gentle reminder a day, at the time you choose.
It never scolds you for a day off. Off by default.

The time MU:note counts is the time we practiced together.
Practice done without the app is still practice.
