This test takes about 3 minutes. The app plays a note, you sing it back, and you say how it felt. Step by step it finds your lowest and highest notes and, more usefully, your comfortable range: the notes a song should stay inside.
- Use headphones if you can, so the mic hears you and not the reference tone.
- A quiet room helps. Sing on an open "ahh" at a normal speaking volume.
- Don't push. If a note hurts, scratches, or cracks, mark it and stop.
- Your audio never leaves this device. Nothing is recorded or uploaded.
Lowest note held: - | Highest note held: -
Practice: match the note
Hold a key (click, touch, or type the letter shown) to hear a note. It plays for as long as you hold it. Then sing it back on an "ahh" and hold it steady. The needle shows how far flat or sharp you are in cents: 100 cents is one semitone (one piano key, about 5.9% in frequency), and under 10 cents (0.6%) is dead on.
Testing a phone, laptop, or mic: open this page on two devices, hold notes on one, and watch the other. A steady tone should read the right Hz with clarity near 1.00. Small speakers can't play the lowest notes, but their harmonics still carry the pitch.

New to music? How note names work
Notes are named with letters C D E F G A B, plus "sharps" (C# = a half step above C) for the black piano keys. After B the letters start over, one octave higher. An octave is a doubling of frequency: A3 is 220 Hz, A4 is 440 Hz.
The number is the octave. C4 is "middle C" (261.6 Hz), the middle of a piano. Most adult men speak around 85-155 Hz (roughly E2-D#3), most women around 165-255 Hz (E3-B3).
A semitone (half step) is one piano key, black or white: a frequency ratio of about 1.059. 12 semitones make an octave. A typical pop melody spans 12-18 semitones.
Comfortable range (singers call it tessitura) matters more than extremes. A song in the wrong key for you is the most common reason a song feels "unsingable". Any song can be moved (transposed) to fit your range.
