I know that tuners seem really basic, but if you ever have to try tuning something like a piano or 12-string guitar, you might consider downloading a dedicated application.
I needed something different when I discovered that my guitar tuner wouldn’t properly identify the range of notes I needed to tune my piano. Two tuners that I tried were FMIT and lingot. I found lingot to be very plug and play oriented. I just had to plug my microphone in, and it immediately recognized it. I got FMIT working, and it seemed more configurable, but I think that I liked lingot better
