Free coaching session for every new account, no credit card required. ## Free tools (no signup, browser-based, nothing recorded) - [Pitch Accuracy Test](https://performancecoach.ai/tools/pitch-test): Sing one note for 8 seconds and get an instant pitch accuracy score (% of time within 25 cents of your note), plus one insight about your pitch habits. - [Vocal Range Test](https://performancecoach.ai/tools/vocal-range-test): Sing your lowest and highest note and get your vocal range (low note to high note), octave span, an estimated voice type (bass to soprano), and a famous-singer match.
