Master Your Pitch Control
Singers and instrumentalists rely on subtle adjustments to stay in tune. The intonation tracker gives you instant visual feedback on your pitch accuracy—measured in cents—so you can identify and correct tendencies before they become habits.
In the app
Here are some things that are even better in the app.
-
Custom reference tunings
Set A4 to your own reference tuning.
-
Transposition
Shift the displayed note by up to an octave (e.g., to match trumpet note names).
-
Better form factor
Improved portability, performance, and diagram quality.
The Full Experience
What changes in your practice
Knowing you sang out of tune is not much use on its own. Knowing you always land a few cents flat on the way up is.
Your error has a shape
Zoomed to fifty cents either side of center, the trace shows the scoop at the start of a note, the sag in the middle, and the drift at the end.
Held notes label themselves
Sustain a pitch for about half a second and its name is written onto the center line, with the one you are on picked out in gold.
No score and no pass mark
It will not grade the take or choose your next exercise. It shows what you did and leaves the decision to you.
