## What is NoteCheck?

No ads. Fully offline. No account needed. Open the app and hear your reference pitch instantly — a lightweight tool built for the moments right before you go on stage.

■ Who it's for
・Vocalists who need a reference pitch before a set
・Guitarists/bassists tuning by ear or checking a phrase's pitch
・Keyboardists who want a quick reference tone
・Any musician who needs a quiet, instant pitch check backstage

■ How it works
Tap a note button or the keyboard — the note plays immediately. Turn on Sustain mode and the note keeps ringing so you can check pitch hands-free.

■ Features
・No ads — zero interruptions
・Works offline — no network, no tracking
・No account — install and go
・2-octave keyboard + 12 note-name buttons
・Sustain mode — hold a note as a running reference pitch
・Large Now Playing display — read the note name at a glance backstage
・Dark mode only — built for dim backstage lighting

Not an instrument app. Not a tuner app. A dedicated tool for the 30 seconds before you go on.
