## What is Vibrato Check?

Sing one held note and know if your vibrato is free.

Between lessons you practise alone, and it's hard to hear your own vibrato: is it a free, even wave, a fast nervous flutter, or a slow wide wobble? Vibrato Check listens to one held note and tells you in plain words, with one thing to try next.

HOW IT WORKS
• Hold the button, sing an "a" on one note for 3–8 seconds, and let go.
• Get a verdict: Free vibrato, Fast & narrow, Slow & wide, Uneven or Straight tone.
• See the numbers behind it: rate (Hz), width (cents), evenness and the note you sang.
• Tap the wave to feel your vibrato as haptic pulses at its real speed.

TRACK YOUR PROGRESS
• Save takes and see your daily vibrato rate over 7 or 30 days.
• Pin a take your teacher liked as your target and compare new takes with it.
• Play back saved takes, or share the audio with your teacher.

MADE FOR PRACTICE AT HOME
• Measure your room's noise once; sounds below the threshold are ignored.
• Classical, musical theatre and pop presets, and adjustable tuning (A4).
• Works in Dark Mode and with VoiceOver.

PRIVATE BY DESIGN
No account, no ads, no tracking. Your voice is analyzed on your iPhone and never uploaded; recordings are kept only when you tap Save.

Vibrato Check is a practice tool, not medical advice.
