### 5/5 — Wonderful!

*2023-06-19*

I was looking for a Just Intonation tuner.

This provides that and allows me to thankfully adjust they key as well.

A can also be tuned to outside of 440Hz.

The best part is that it is free of ads and it provides a frequency chart of where each note should be!

This makes it very easy as a reference tool when working with digital instruments!

Thank you makers!
