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 adds extra practice tools, by monthly or annual subscription or a 24-hour reward video.
What’s new & improved in v1.48 · September 2026
- •Premium subscriptions (new) — choose an optional monthly or annual plan to keep Premium features active and banner ads hidden. Available rewarded videos still offer 24 hours of Premium access. Help includes purchase restoration, subscription management, and offer-code redemption.
- •Your Practice (new) — a free, on-device practice summary with your current streak, estimated active time this week and month, and a daily activity strip. Open it anytime from Help.
- •Pitch Accuracy recent tuning (improved) — see recent tuning for the note you are playing alongside session averages, so changes in your intonation are easier to spot.
- •Clearer metronome sound (improved) — refined metronome sounds and clearer spoken counts make the beat easier to follow, and the metronome now follows your device volume buttons.
- •Easier navigation (improved) — highlighted Tuner and Metronome buttons are easier to find, and Score practice can start from a C major example when Premium is active.
- v1.47 · September 2026
- •Pitch Replay (Experimental) (new) — record a phrase, then hear your Original take and a Pitch Corrected replay with a live tuner view and a deviation timeline. One saved recording is free for everyone; Premium adds more saved recordings and per-note Original/Corrected comparison.
- •Pitch Accuracy (Experimental) (new) — open Accuracy from the Tuner to see every detected note grouped by octave and color-coded by average tuning — live, or from a saved Pitch Replay take with an adjustable time range. On iPad, Accuracy fills the screen with a two-pane landscape layout.
- •Score View passage loops (new) — tap the first and last notes of any passage to repeat that range, with directional brackets marking the boundaries and a one-time guide showing how it works.
- •Listen Mode (Experimental) with Saved Takes (new) — play a selected Score passage at your own tempo. MetroTune waits for the first note, follows you forward, then marks pitch, rhythm, and matched notes on the score. Saved Takes keep audio and results together on your device.
- •Every sound profile, voice, and tuner tone is free (improved) — all current metronome sounds, counting voices, and tuner tone profiles are now available to everyone.
- •Smarter Scale Practice feedback (improved) — Echo Mode now follows your full Scale Practice routine, listens on the beat, and gives clearer pitch guidance when you need another try. Pitch Checker can also cue the next scale note after you confirm your pitch.
- •Steadier timing at fast tempos (improved) — high-BPM playback no longer drifts slower, polyrhythm lines stay aligned more closely, and BPM limits now follow the rhythm you choose, with a clear notice when the tempo is adjusted.

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 control
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.
New in the Tuner · Experimental
Pitch Replay: hear your take, then hear it corrected.
Record a phrase, then play back your Original take and a Pitch Corrected version with a live tuner view and a deviation timeline. Recording, full replay, and one saved recording are free for everyone; Premium adds more saved recordings and per-note Original/Corrected comparison. Recordings stay on your device.
See which notes stay in tune across your practice.Experimental
Pitch Accuracy listens as you play and groups every detected note by octave, color-coded by average tuning: in tune, good, close, or needs work. Watch it live from the Tuner, or open a saved Pitch Replay take and adjust the time range to focus on any section. Pitch data is analyzed on your device, and this mode does not save audio.
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.
