We hash the visible text on every check, so a redesign registers and a rotating advert does not. An app that has not changed in a long time is not necessarily abandoned — but it is a fact worth knowing before you depend on it.
What it does
IntervalKit is a browser music-theory kit with harmony, scales, chords, and compose modes. Instruments include guitar, piano, cello, and alto recorder. You pick a tonal center and complexity, then hear how that harmony sounds.
What people say
No reviews yet.
We would rather show none than invent them.
Embed this status
Put it in your README. It updates itself every time we check, and links to your verification record — evidence a stranger can read, not a page selling them something.
