Pitchtrail: Vocal Pitch Meter

Open Pitchtrail and sing. Your pitch appears at once as a trail across note lanes, with the note name, the octave and how many cents sharp or flat you are. No questionnaire, no account, no ads.

• Live pitch monitor — big note display, cents meter with an in-tune band, Hz, and a scrolling trail on piano-roll lanes. Tap a lane to set a target note. Pause and drag back through the last 60 seconds.
• Built for real voices — low notes are tracked too, so basses and baritones are covered. Octave jumps and stray notes are filtered so the trail stays steady.
• Vocal range test — sing (don't speak) your lowest and highest comfortable notes, redo either step as often as you like, and see your range, its span and the closest voice type (an estimate, from bass to soprano).
• Reference tone and drone on any note from C2 to C6.
• Record a take and listen back with its pitch curve, the cursor following the audio. Three recordings are kept without paying.
• Exercises that fit your voice — Hold the note and Five-note scale start in a key chosen from your range test, at slow, normal or fast tempo. Each note plays first, then you sing it back, so the guide tone never spoils your score. See your score and whether you tend to go sharp or flat.
• Settings for choirs and teachers: reference pitch A4 from 430 to 446 Hz, note names as letters (C D E, or with H) or solfège (Do Re Mi), in-tune range ±10/±20/±30 cents, and a high-sensitivity microphone mode.

The monitor, range test, tones, two exercises and three recordings stay available without Pro. Cancel a subscription anytime in Google Play.

Privacy: your voice is analysed on your phone and is never uploaded. Recordings stay on your phone.

Tip: use headphones when a drone or guide tone is playing, so the speaker doesn't reach the microphone.
