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

This is a browser instrument using rational numbers. Green keys on the right play sounds, and purple keys on the left change the harmony. Sweeping across keys is designed to sound consonant; you can record and play back.

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.
