PitchFlow: Vocal Pitch Trainer

PitchFlow helps you see how your voice moves in pitch and practice from a comfortable note. Use the 30-second check for a quick view, or keep the continuous pitch view running until you stop it. The graph retains the latest 60 seconds. Leaving the app stops foreground microphone capture. Listen to a reference tone, wait for a silent count-in, then sing it back. Choose a comfortable starting note and 40, 60 or 80 BPM. Five optional stages move from one note and holding it to short two-, three- and five-note patterns. Repeat or change stages whenever you want. A result shows how much of the scoring interval contained a reliable pitch, time near the selected target, and pitch difference. After another attempt under the same conditions, compare the two traces on a shared scale. If there is too little usable sound, PitchFlow explains the gap instead of inventing a score. Core pitch analysis runs on your device. Recording is off by default. If you opt in, audio is written to a private temporary file and you can save or discard it after practice. Saved recordings can be played, deleted and exported. Optional recording is limited to 30 minutes; this is separate from measurement time. Basic pitch viewing, practice and retries remain available without opting into recording. Ads and consent data handling are separate from pitch analysis. Chords, accompaniment, very low or weak signals can produce uncertain results. PitchFlow does not diagnose vocal health or rate singing ability.
