MuseTuner is a chromatic tuner and metronome for twelve instruments and the human voice. It includes dual-mode pitch detection, seven swipeable tuner displays, an interactive headstock tuner for guitar and ukulele, live fingering charts, a vocal range chart, Circle of Fifths and Scale Finder tools, a music key changer for transposing instruments, a digital note player, and a built-in metronome. The app works fully offline.

— PITCH DETECTION —

Two detection modes are provided for different scenarios. Fast mode is optimised for quick response on bright instruments. Smart mode is optimised for stability on low brass, double-stops, and noisy environments. A benchmark mode in the app lets you compare the two on the same input.

— SEVEN TUNER DISPLAYS —

Swipe between seven visualisations of the same detected pitch:

• Classic gauge with needle.
• Wave-of-bars meter with colour-coded zones.
• Vertical pitch ladder with a floating Hz tag.
• Pitch trail — scrolling cents-over-time graph for vocalists and practice.
• Animated waveform synced to the detected note.
• Live oscilloscope showing the input instrument's tone.
• Interactive headstock tuner (guitar and ukulele).

— INTERACTIVE HEADSTOCK TUNER —

When Guitar or Ukulele is selected, the app shows a photo of a real headstock with tappable tuning pegs. Tap a peg to hear its reference note. Pluck a string and the app identifies which peg you are tuning. Tap-to-lock onto a specific peg to focus.

Guitar tunings: Standard, Drop D, Half-step down, Full-step down, Open G, Open D, DADGAD.
Ukulele tunings: Standard High-G, Low G, Baritone, D Tuning.

— TWELVE INSTRUMENTS WITH LIVE FINGERING —

Universal · Guitar · Ukulele · Trumpet · French Horn · Violin · Cello · Piano · Flute · Piccolo · Saxophone · Clarinet.

Each instrument has its own reference-note voice and a live fingering chart that highlights the matching position when MuseTuner detects your note. Tap any instrument's info button to view its history, range, and playing technique.

— VOCAL RANGE CHART —

For singers, the fingering chart is replaced with a live vocal range chart that maps the detected pitch onto standard voice-classification bands (bass, baritone, tenor, alto, soprano). Tap the Guide button to open the full-screen vocal range view with live pitch tracking.

— CIRCLE OF FIFTHS AND SCALE FINDER —

Two music-theory tools are included. The Circle of Fifths shows major and minor scales, accidentals, and engraved clef plus key signature on a hand-drawn staff for any key you tap. Scale Finder reverses the lookup — select a scale and see which keys contain it.

— MUSIC KEY CHANGER —

Concert-pitch transposition for transposing instruments (Bb trumpet, Eb saxophone, F horn, D clarinet, and more) is handled automatically. Tap KEY, select your instrument's key, and the displayed note matches the written note on your sheet music.

— DIGITAL NOTE PLAYER —

The full piano keyboard (eight octaves, C1 to B8) is available for note playback through a clear voice. Useful for ear training, intonation work, finding a starting pitch, or confirming a note before tuning.

— METRONOME —

Includes time-signature support, customisable BPM, and downbeat accent.

— OFFLINE OPERATION —

The app works without an internet connection. No account is required. Your last instrument, key, tuning preset, and display preference are saved automatically.
