Best free one

This is the best free one out there. Its nice to have the octave as well as the note. I knew something was wrong with my wifes violin but other tuners just told me the 3rd string was playing A. This one told me I was playing A3. So we tuned to A4 and now it sounds nice. I also like that it shows half notes too. Its also nice to be able to select the tuning style as well as how each string is tuned to; concert =440hz vs baroque =415hz. No other tuner does that.
