Read full description

See and hear how music fits together. Harmonizer turns musical relationships into a colorful, interactive grid. Tap a hexagon to hear a note, or tap the triangle between three notes to play a major or minor chord. Sing or play a single note on an instrument, and watch the detected pitch light up. EXPLORE NOTES AND CHORDS Discover how neighboring notes connect through perfect fifths, major thirds, and minor thirds. Major and minor chords form triangles, making harmony something you can see, hear, and explore with your fingers. SEE YOUR VOICE Use the microphone to highlight the pitch you sing or play. Listen to a note, try matching it with your voice, and explore the connection between sound and color. CHOOSE YOUR LABELS Show note names or Movable Do syllables, with your choice of tonic. Keep labels visible, show them only when notes are active, or hide them to focus on the colors and sounds. EXPLORE YOUR WAY Choose from playing, pitch detection, or a mode that listens when you stop playing. Adjust the grid size to suit your screen and how you like to interact. HEAR HARMONY DIFFERENTLY Harmonizer uses Shepard tones—layered sounds that emphasize a note’s identity without a distinct octave. Every hexagon with the same note name produces the same sound. For curious beginners, students, teachers, and musicians, Harmonizer offers a hands-on way to explore pitch, chords, and musical patterns. No music theory knowledge is needed to start: touch a note and listen. Pitch detection requires microphone access.

Verdict

The call

The clearest difference is price: Harmonizer at Free against Singing Fingers's $0.99. Harmonizer also leads on rating (4.1 vs 3.5) and update cadence (every 33 months vs every 96 months). Singing Fingers's advantage is device support (3 vs 1) and iOS requirement (10.0 vs 17.0). On review sentiment, ratings volume, ads and in-app purchases there is nothing between them.
