Everyday practice
Analyze
See live waveform activity against musical gridlines, then freeze the recent take for closer review.
Percussion timing, made visible
Hear the pulse.
See your placement.
BeatTrace keeps your microphone waveform, the metronome grid, and detected attacks together—so a vague timing problem becomes something you can hear, see, and work on.

The practice loop
A metronome gives you the grid.
BeatTrace keeps the take.
Everything centers on one useful question: what did your attack do relative to the time you meant to play?
- 01
Set the pulse
Choose the BPM, meter, subdivision, and Sound Map that fit the passage.
- 02
Play a focused take
The click, timing grid, microphone waveform, and detected attacks share one timeline.
- 03
Freeze and inspect
Keep the take on screen, zoom into the waveform, select a loop, and listen again.
One shared timeline
What you hear, see, and measure stays aligned.
BeatTrace’s core system schedules the click, draws the musical grid, maps microphone input, and scores detected attacks from one audio-sample master timeline. The redesign changes the experience around that system—not the system itself.
- Waveform gain
- Makes quiet playing easier to see without changing detection or scoring.
- Sound Map
- Hear the quarter-note pulse while still seeing a finer subdivision grid.
- Frozen review
- Pan, zoom, select a loop, and revisit the exact passage.

Inside BeatTrace
One instrument. Four ways to practice with intention.
Start with the everyday practice view. Open more structure only when the work calls for it.
A clear assignment
Guided Tests
Clapping, Blind, Cold Start, and Microscope Check flows make each listening and playing phase explicit.
Carry more of the time
Independence Ladder
Progressively reduced click information asks you to maintain subdivision with fewer external landmarks.
Keep the takeaway
Logs & reports
Save guided results locally and return to a plain-language summary instead of a vague memory of the session.
Built for precision, not judgment
Timing evidence is useful.
It is not a verdict on the musician.
● It shows
- Detected attacks against the grid you selected
- Early, aligned, and late timing direction
- Waveform context around each attack
- Signed millisecond feedback in guided results
- Patterns worth testing in the next repetition
× It does not
- Grade musicality, expression, tone, or technique
- Compare you with other players
- Replace your ear, teacher, or ensemble context
- Manufacture a score when the audio route is untrustworthy
- Promise the same outcome for every musician
You bring the musical decision. BeatTrace keeps the timing evidence legible.
From the stand
“I built BeatTrace around a problem I meet in my own playing and teaching: ‘I think I’m rushing’ is hard to practice. Seeing the take gives the next repetition a specific job.”

Common questions
The honest pre-launch answers.
BeatTrace is still in development. Price, public availability, and release timing have not been announced.
What is BeatTrace?
BeatTrace is a native iPhone and iPad practice app in development for percussionists. It places detected note attacks, the microphone waveform, and the metronome grid together so you can study what happened in a short take.
Is BeatTrace available now?
Not publicly. This is a waitlist and product-validation page. No public App Store release date has been announced.
How much will it cost?
No price, pricing tier, trial, or checkout has been announced. Joining the waitlist is not a purchase, reservation, or promise of availability.
Does it judge whether my playing is musical?
No. BeatTrace makes one timing relationship visible: detected attacks against the timing grid you selected. It cannot grade musicality, replace listening, or decide whether a performance is good.
What audio setup works best?
The built-in speaker or wired audio are the intended setups for timing measurement. Bluetooth can be used for listening, but measurement is paused when latency would make the timing feedback untrustworthy.
Does this waitlist collect my practice audio?
No. The waitlist stores only the email address, selected audience option, consent record, and signup time you provide.
