Vocal Pitch Recorder

Vocal Pitch Recorder turns your phone into a visual singing coach.

Sing into your microphone and watch your pitch drawn across a musical scale in real time. After recording, review each take with detailed offline analysis so you can see what you actually sang — not just a rough estimate.

Perfect for singers, vocal students, karaoke fans, songwriters, and voice coaches who want clear feedback between lessons or rehearsals.
