Built for real singers, not just vocal technicians
A range result is only useful if you can reproduce it. That’s why we separate “I hit it once” from “I can sing it on purpose.”
What “comfortable” means here
Your comfortable range only counts notes you can hold steadily for about 2 seconds (sustainable & controllable). This filters out “lucky” one-offs and focuses on what you can reproduce on purpose.
Brief peaks—like short shouts, squeaks, or momentary pitch spikes—can inflate an “extreme high note” without improving real singing. We keep extremes visible, but we don’t let them overwrite the usable baseline you’ll rely on for repertoire and technique.
Stable notes only
Comfortable range prioritizes notes you can sustain (about ~2s), not one-off spikes.
Separates extremes
You can still see your absolute lowest/highest attempts, but they don’t overwrite the usable baseline.
Designed for real use
The goal is a range you can apply to practice and repertoire decisions, not a brag number.
What you get
Concrete fields, charts, and shareable output.
Keyboard chart + note names
Your result appears as highlighted keys with note names (and pitch notation), so you can screenshot and share it. The chart is designed to be readable at a glance—useful in lessons, rehearsals, or when comparing recordings.
How it works
Windows checklist
Settings → Privacy & security → Microphone (allow your browser). Then: pick the correct input device in the browser, disable aggressive “Enhancements”/noise suppression if it clips pitch, and try wired headphones to avoid feedback.
macOS checklist
System Settings → Privacy & Security → Microphone (enable for your browser). Set the right input in Sound, keep input volume moderate, and avoid playing reference notes through speakers (echo can confuse detection).
iOS / iPadOS checklist
Use Safari. Allow Microphone permissions when prompted. Disable Low Power Mode if audio stutters. If pitch jumps around, use headphones and move slightly away from the device mic.
What Singers Say
Short, practical feedback from real users.
This was the first tool that separated my extreme notes from my comfortable range. That made the result actually usable.
Emily R.
Sings in a community group
"The chart helped me understand where my voice is most consistent, instead of guessing based on one lucky high note."
Carlos M.
Indie band musician / Using the tool for 6 months
"We use it as a reference point during the season. The visual chart helps students focus on consistency and healthy technique."
Dana K.
Music teacher / Works with 60+ students
"The instructions were clear and gentle. I liked the focus on comfort instead of forcing high notes."

Karaoke fan / Started singing regularly last year
