- Guitar, bass, and other string-instrument players
- Worth noticing
- The page says the app requests microphone access only, with no network permission, and distinguishes silence from noisy input.
Field notes
The page says the app uses Atkinson Hyperlegible, supports screen readers, and remains readable in a high-contrast mode that does not rely on color. It lists six instruments and 18 tunings, and describes an input-level indicator to help explain when a played note is too quiet. The microphone-only permission and no-network statement are claims made on the page.
