Broken

Stopped working with the latest update. Doesn’t make any sound at all.

Doesn’t work anymore.

Maybe it’s something I’ve done but since the latest update I can’t hear any sound anymore. Used to use this all the time. Maybe it will get worked out.

Pretty good.

You get four sound options to hear the pitch...the horn and violin sounds are pretty cheesy, the piano sound is sharp (I tested it against my real electronic tuner) but the sine wave is just fine and my favorite.
Could be handy in a pinch, plus it’s free so who can complain?

Almost great

Very useful BUT the piano sample is sharp (not 440)
