Pitch Monitor

See your pitch in real time

Sing into the mic and watch your pitch drawn live on screen — you instantly see whether you're on note.

The problem

The hardest part of practice is not hearing your own off-pitch moments. HengHeng turns your voice into a visible curve with cent-level deviation, so your ear's blind spot becomes visual feedback.

How it works

Three steps

  1. 1

    Open the page and allow microphone access

  2. 2

    Hold any sustained note

  3. 3

    Read the curve and cents, nudge toward center
