PitchBar: Vocal Pitch Trainer

See exactly how close you are to pitch-perfect, note by note — with a karaoke-style accuracy bar built for singers and choirs alike.

Pitch Trainer helps you sing every note in tune — whether you're warming up for karaoke night or rehearsing with your choir. Sing into your phone's microphone and watch your pitch line up (or drift) against the note you're aiming for, in real time. No recording, no waiting — just instant visual feedback. TUNER Play any reference note on the built-in keyboard and match your voice to it. A color-coded chart shows exactly how far off you are, in real time. PRACTICE Choose from ready-made vocal warm-ups (scales, chromatic runs, long tones) or build your own custom phrase. Sing along and get scored note by note:

• Within ±15 cents: pro-level accuracy
• Within ±50 cents: a solid, karaoke-passing performance
• Beyond that: you'll see exactly where to focus next Track your personal best on every phrase, and review a full breakdown after each attempt, including which note needs the most work. NOTE NAMES, YOUR WAY Switch between three notation styles at any time: hi/lo vocal notation (hiA, mid2C), solfège syllables with octave numbers, or international pitch notation (A4, C5). PRIVACY FIRST Your voice is analyzed entirely on your device, in real time. Nothing is ever recorded or sent anywhere. Available in Japanese, English, and Simplified Chinese.
