Easy and accurate

I have tried several iPhone and iPad tuners, and so far this one has proven to be the easiest to use to accurately tune my acoustic 6-string (steel) guitars. I also find the analog dial display to be very intuitive. The only shortcoming Ive found is the display will not rotate for landscape orientation on an iPad, which is annoying but does not alter functionality. One hint- iPhone tuner apps only work well in quiet environments. Ambient noise distorts their accuracy.
