Metronome Hero

The metronome that listens back.

Metronome Hero scores the hits and note attacks you play, shows where you land relative to the beat, and can automatically adjust the tempo to help you improve.

Note Highway

See where you land

Rush a note and you see it instantly — while your hands still remember the mistake. No listening back to a recording. No waiting for someone to tell you. You feel it and you see it at the same time.

A 7-zone timing spectrum tells you not just whether you’re on beat, but how far off and in which direction.

Play musically, not mechanically

Setting the quantization to sixteenths doesn’t mean you have to play every sixteenth note. Play your own rhythms — long notes, short notes, rests, syncopation. Metronome Hero only scores the notes you actually play. Take a breath, leave space, be musical. All that matters is that when you do play, you’re on beat.

Everything you need to level up

Directional Feedback

See that you consistently rush the backbeat, or lay back on beat 3. That specificity turns repetition into improvement.

Fight the Rush

Rushing is the most common timing problem — and the hardest to feel yourself doing. Metronome Hero skews its hit zones so that laying back is scored more generously than pushing ahead. Over time, this trains you into the pocket naturally, without thinking about it.

Accuracy & Consistency

Two independent metrics track your playing. Accuracy measures how close each hit lands to the beat. Consistency measures how steady you are over time. Five difficulty levels — from Chill to Pro — tighten both thresholds.

Musical Tap Sounds

Every tap or MIDI hit can trigger a musical note. Choose from 10 instrument voices or 8 drum sounds. Set a chord voicing so each beat lands on the same notes, reinforcing your timing.

Session Tracking

Every session records accuracy, rating distribution, tempo progression, best streak, and duration. Review history on a practice calendar with iCloud sync.

Flexible Time Signatures

Practice in anything from 1/4 through 5/4, plus 6/8 through 16/8. Add subdivisions from eighths to thirty-seconds and swing feel from subtle to hard shuffle.

See your rhythm, your way

Each view shows your timing accuracy differently — some zoom into every hit, others reveal patterns over time. Tap to switch mid-session or set auto-cycling on level changes.

Note highway 3D visualization

Note Highway

A 3D perspective view where the horizontal axis is your timing — very early on the left, pocket in the center, very late on the right. Hits recede into the distance as new ones arrive.

Half-pipe parabolic visualization

Half-pipe

A parabolic curve where hits roll toward the center when you’re in the pocket and climb the walls when you rush or drag. The shape makes timing feel physical — like a skateboard half-pipe.

Playhead visualization

Playhead

A sweeping bar moves left to right. The vertical axis is your timing — early notes appear above the center line, late notes below. Simple, clear, immediate.

Scrolling history visualization

Scrolling History

A scrolling timeline where the vertical axis shows your timing — early notes rise above the center, late notes fall below. Watch your rhythmic tendencies emerge over time.

Tubular polar-coordinate visualization

Tubular

The largest area devoted to the timing axis, mapped around the circumference of a circle. The most visually immediate view — you can see exactly where in each accuracy zone every hit lands.

Circular playhead visualization with wave effects

Circular

A radial clock-face sweep with rippling wave effects. Instead of a zoomed timing axis, it shows the most notes at once — beautiful patterns that reveal your overall consistency.

Level up — and level down

It gets harder as you get better, and easier when you struggle. Automatically.

ACCURACY
CONSISTENCY

Two independent meters track your performance in real time — accuracy measures how close you land to the beat, consistency measures how steady you are over time.

Level Up

When your accuracy, consistency, or both cross the threshold, the tempo bumps up automatically. Choose which metric drives progression — or require both for the ultimate challenge.

Click Sound Randomization

The click sound changes every time you level up or down — an unmistakable auditory signal that something just shifted, even when you’re not watching the screen. It also prevents ear fatigue during long sessions.

Level Down

When your metrics drop below the threshold, the tempo backs off. No shame — it’s smart practice. Spend more time at tempos where you’re challenged but not overwhelmed.

Interval Training for Rhythm

Combine level up with level down and you get interval training — the tempo pushes you to your edge, backs off to let you recover, then pushes again. Your comfortable tempo climbs session after session.

Detailed Session Summary

When you stop, Metronome Hero shows you exactly how the session went.

  • Duration, total hits, and overall accuracy
  • Rating distribution across all 7 zones

Play any instrument. Three ways in.

Tap the screen, use your microphone or audio interface, or connect a MIDI controller.

🖐

Tap

Tap the screen, click the mouse, or press keyboard keys. Perfect for percussion fundamentals and warming up anywhere.

🎤

Audio

Use the built-in microphone or plug in your audio interface. Play drums, guitar, piano, voice — anything with a clear attack. Adaptive auto-gain handles sensitivity automatically, and latency calibration helps line up what you hear with what gets scored.

🎹

MIDI

Connect any MIDI controller via Bluetooth or USB. Keyboards, drum pads, electronic kits — play your own instrument and let Metronome Hero score your timing with the most direct input path.

Challenges that build real musicians

Professional practice techniques built right into the app.

Play / Mute Cycling

Alternate between measures with clicks and measures of silence. When the clicks come back, are you still in time?

Backbeat Only

In 4/4, only beats 2 and 4 play. The pocket. The groove. Train what matters most.

Random Click Drop

Up to 50% of beats go silent. Can you hold steady when the safety net disappears? Forces you to internalize the pulse.

Progressive Click Drop

Each level-up removes more clicks from the pattern. Combined with auto-tempo, a practice session that evolves with you.

One app. Every Apple device.

Metronome Hero meets you wherever you practice. All your sessions are stored on iCloud, so every device shares the same practice history.
