Noteon - Current Note Detector

See the note you’re playing in real time. Noteon detects clear single pitches and displays them big, bright, and easy to read.

Noteon is a simple, bright note detector for musicians.

Open the app, allow microphone access, and play a clear single note. Noteon listens in real time and displays the detected note as a large letter on a full-screen color background, making it easy to read while practicing, teaching, tuning, or using an older iPhone as a dedicated note monitor.

Noteon works with violin and other instruments that produce a clear single pitch, including guitar, piano, voice, and more.

Features: • Real-time note detection through the microphone • Large full-screen note display • Unique background colors for each note • Simple design with no clutter • Keeps the screen awake while the app is open • Great for practice rooms, lessons, and reuse of old iPhones

Noteon is designed for clear single notes. Chords, noisy rooms, or very fast passages may affect detection.
