Singing is fun. Singing off-key isn't.

While you sing, it's hard to hear whether you're a little flat or sharp. Singler shows you the moment it happens. Your ear learns what "right" sounds like, and your voice follows.

  • See it, don't guess

    Your pitch as a line, the target as a band. You see right away which way to correct.

  • Grows with you

    The tolerance gets tighter as you improve, and looser when something isn't clicking yet.

  • Tips that fit

    After each round you get specific advice, for example when you tend to scoop up into notes.

How it works

  1. 1

    Set up your mic

    A 10-second calibration so Singler can tell your voice apart from room noise.

  2. 2

    Find your vocal range

    Slide down and up. Singler finds your comfortable range and adapts every exercise to it.

  3. 3

    Practice with live feedback

    Hit notes, hold notes, sing melodies: you see right away how accurate you are.
