Stimmi: Note Tuner for Kids

wunderfarm

About this app

Stimmi shows children what they are playing — right on the staff.

Instead of needles and numbers like a classic tuner, Stimmi shows the
note you play or sing on a musical staff. The note is called Notli and
has a face: hit the pitch and Notli turns green and sings along. Almost
there? Notli looks focused. Not yet? Notli keeps smiling — no red
"wrong", no frustration.

FREE PLAY
Just start playing or singing: Stimmi recognizes the tone and shows it
as a note on the staff — with its name, an encouraging hint ("almost! a
little higher") and a colored zone bar that shows how close you are.

PRACTICE TARGET NOTES
Stimmi shows a target note and the child plays or sings it. Hold the
tone to fill the ring and collect stars — with a little celebration
after every note.

MADE FOR THE MUSIC STAND
Put the phone sideways on the stand: in landscape the staff gets nice
and wide, and detection keeps running while you rotate.

WHO IS IT FOR?
Children and beginners — with recorder, violin, piano or their own
voice. Stimmi listens from low children's voices up to the high notes
of recorder and violin.

MADE FOR KIDS

• Works offline — no data collection
• Big elements, little text, friendly feedback
• Child-friendly tolerance: well-hit notes count as hits

music along the way.
