Reference drone: sing against a steady note
How to use the graph: the line is your voice over the last 8 seconds. Aim for the centre of a note line. The meter shows how many cents (hundredths of a semitone) you are sharp (+) or flat (-). The "steady hold" counter measures how long you keep one note without wobbling: a good breath-support test. Try holding a note for 10 seconds with a drone playing.
Find your vocal range
Press Start, then slide slowly down to the lowest note you can sing comfortably and hold it for a second. Then slide up to your highest comfortable note and hold it. Notes only count after you hold them steady for half a second. Do not strain.

Tip: after you guess, sing the interval back using the live graph. If you turn on Quarter-tone mode above, "All intervals" also includes the neutral intervals used in Arabic maqamat.

Pitch detection uses the YIN method on your microphone signal, with no audio sent anywhere. Quiet room, headphones, and a mic a hand-width from your mouth work best. Exercises play the guide note first and mute the detector while it sounds, so the speaker does not confuse it. Scores count the share of the listening window you spent within the accuracy limit, so wobbling and late starts reduce the score; the app also tells you whether you tend to sing sharp or flat. Maqam exercises (Rast, Bayati, Hijaz, Saba, Nahawand, Kurd) use true quarter-tones on the sound of the maqam starting on your chosen note. This is a practice aid, not a replacement for a teacher; stop if your voice feels tired or strained.
