Real notation, not tab-style grids
Score View renders a real staff with clefs, key signatures, ledger lines, and accidentals — so practice feels like reading music, not configuring an app.
MetroTune™
Metronome, tuner, and scale practice on one screen.
Real notation, live pitch detection, and a click track working together — so you can build timing and intonation in the same practice loop. Free core tools. No account required.
Free core tools stay usable without an account. Optional premium unlocks add extra practice tools and ad-free time.
What’s new & improved in v1.46 · June 2026
- •Pro tuner: Just & Pythagorean temperaments (new) — choose Equal, Just, or Pythagorean temperament in any major or minor key, with note names spelled to match the selected key.
- •In-tune highlight (new) — the note name brightens and glows as you land on the pitch, with adjustable range, glow, and color.
- •Reference tones with a perfect fifth (new) — optionally sound a fifth above the reference note for hearing intervals while you tune.
- •Polyrhythm support (new) — Add a second rhythm line at the same BPM, with its own pattern, Sound Profile, rests, and per-note customization.
- •Better tablet landscape layouts (improved) — Refined landscape layouts for iPad and Android tablets across Metronome, Tuner, and Score View.
- •Smoother playback & notation (improved) — Better playback timing, scale audio starts, Score View notation, and overall practice stability.
- v1.45 · May 2026
- •Per-beat & per-subdivision sounds (new) — customize individual beats and subdivision notes, assigning a different sound or muting them directly from the metronome pattern, while the BPM stays consistent.
- •Clearer sound customization (improved) — a long-press/edit workflow, reset controls, easier cancellation, and sharper visual indicators for custom and muted notes.
- •More reliable voice + click playback (improved) — combined voice and click setups now wait for samples to be ready, so notes no longer drop.
- •Sharper Score View key signatures (improved) — improved minor-key, arpeggio, and key-cycle notation, with cancellation naturals where appropriate.
- •Smoother scale playback on Android (improved) — audio-startup tuning to reduce weak first notes and playback inconsistency.
- •More robust rewarded-ad premium flow (improved) — premium recovers more reliably when an ad close callback is delayed or missing.

What makes MetroTune stand out.
Transpose tuning, built in
Read your written notes on a B♭ clarinet, E♭ alto sax, F horn, or A clarinet — tap-to-play and Scale Practice automatically sound concert pitch.
Ear training built in
Echo Mode turns the tuner into a call-and-response ear trainer. No separate app to download.
Per-beat and per-subdivision sound controlNew in v1.45
Give individual beats and subdivision notes their own sound profile — or mute them outright. Long-press a note to edit it, with clear indicators for custom and muted notes, and the BPM stays put while you shape the pattern.
A composer’s tempo map
Beethoven’s 9th, Mvt. 4 ships as a seed profile — six entries with shifting BPMs and meters — so new users see what a real tempo map looks like.
Score View
Practice scales from real notation, not configuration menus.
Switch to Score View and the staff appears: clefs, key signature, ledger lines, accidentals, rests — the closest thing to opening a method book inside the app. Notes light up as the metronome plays them, so you read and keep time at the same time.
“I specifically wanted a way to check my pitch while working at varying tempos — ensuring my intonation stayed rock-solid as I increased speed.”
A Day With MetroTune
Open the app, hit START — and practice the way you actually practice.
Ten steps through a real practice session. No setup. No account. No permissions wall.
Practice in one tap. No account, no setup.
Tap START and a click plays at 120 BPM in 4/4. Everything else is one tap away from this screen. No account, no permissions wall.
Shape grooves presets don’t ship with.
Pick a subdivision shape — quarters, duplets, triplets, sixteenths — then long-press any beat or subdivision note to give it its own sound or mute it. Shape a groove no preset ships with, in seconds, while the BPM stays put.
Build a scale workout in 30 seconds.
Add scales to the queue in any key. Set count-in beats, loop count, gap between scales. Save the queue as a profile and reload it tomorrow.
Hanon, circle of fifths, arpeggios — already built.
Six categories: Foundations, Major Scales, Minor Scales, Arpeggios, Genre Scales, Drills. Tap any template to load it as a starting point, then customize.
Train your ear without leaving the app.
Echo Mode plays a note, then listens. Match it within tolerance and the next note plays. Miss it and the app re-prompts with the attempt counter. Real ear training, no extra app.
Read your written notes, sound concert pitch.
Transpose the tuner for B♭, E♭, F, A, or ±octave instruments — clarinets, trumpets, saxes, French horns, piccolos, basses. The score stays in your written key, tap-to-play and Scale Practice automatically sound concert pitch, and a TX pill on the reference row shows the active transposition at a glance.
Tune to the harmonics of your actual instrument family.
Five lifelike instrument voices — Tone, Clarinet, Brass, Organ, Bell — each with the correct overtone series and instrument character (bell hum, brass breath, Hammond drawbars). Set A4 anywhere from 392 to 470 Hz with one-tap presets for baroque (415), 430, 432, 440, 442, 444. Choose how long a tapped note plays: 1 to 10 seconds, or hold forever. The note name brightens and glows the moment you land on the pitch, with adjustable range, glow, and color — and the reference tone can optionally sound a perfect fifth above the note, for hearing intervals while you tune.
New in the Tuner
Equal, Just & Pythagorean temperaments — in any key.
Equal, Just, and Pythagorean temperaments in any major or minor key, with note names spelled to match the selected key.
Practice complex pieces the way they’re written.
Multi-entry sequencer with per-step tempo, meter, beat pattern, sound, accents, and measures. The 4th movement of Beethoven’s 9th ships as a seed profile — six entries across shifting BPMs and meters — so you can see how a real piece lays out before building your own.
Easier on the eyes for long sessions.
Six base themes plus six pastel variants. Long-press the play button to swap. Pick the language that fits your daily life.
Double-clap to start. Double-clap to stop.
The microphone listens for two sharp claps in quick succession and toggles playback. Use it when your hands are full — bow, sticks, keys.
Three apps. One tap apart.

Founder’s Note
Built for musicians, by a musician.
I built MetroTune because I wanted a more effective way to practice. I was tired of jumping between separate apps and frustrated by hitting paywalls on the essential tools I needed.
“I specifically wanted a way to check my pitch while working at varying tempos — ensuring my intonation stayed rock-solid as I increased speed.” I also needed a guide to help me master scale intonation, with a reliable reference for every note.
MetroTune is the result: a seamless 3-in-1 tool where the modules work together — on the Tuner page, the metronome ticks, pitch detection runs, and scale notes play in the same session. The essential tools work without an account or a paywall, and any premium extras stay optional. Built to help you master your craft, not manage your apps.
