Pano Tuner - Chromatic Tuner

This app provides many features that couldn't be found before all in one place. You can customize the user interface as well. My favorite features are being able to set A=x amount of hertz. This lets me experiment with historical tunings when I pair it with the temperament feature. I think despite having some advanced features, this app is great for beginners out of the box and doesn't require any technical or theoretical knowledge to use."

I really like Pano Tuner. The display is very precise, and it allows adjustment of the primary tuning frequency to help match hard to tune instruments like pianos. It doesn't have preset tuning sets for guitars like some apps do, but that's not as important to me. It's very sensitive, though, and it picks up people talking in the next room. I also like that is doesn't seem to have video ads that interrupt you while you're tuning your instrument. The ads are small and out of the way. It would be nice to customize the display, but other than that, I think Pano Tuner is the best tuner a smartphone can have."
