Good but

This app is cool but would he better if it talked to determine the pitch.

Great tuning device

I like this app very much! There are few things that could change which would make this the best tuning device :  1. Power-saver by-pass...it is annoying at the moment when you tuning instruments with 50 + strings and the screen blanks out...most other tuners will keep by-pass the power-saver function.  2. It would be great to be able to store different intonation tables on your device and be able to toggle between them. At the moment you have to down load a file from a web-page and load it every time you want a different intonation table. Sometimes I am tuning to mean-tone, just intonation or my own variations 3. It would be good to a bigger range of calibration so as to include A = 415 for baroque music Apart from these points it is incredibly accurate, it does not get "stuck" on pitches as you tune a different string, very easy to read and for this I'm very thankful. It is I think the best tuning device but with updates I would be very happy indeed......Great work HotPaw

Sorry for bad spelling, I have fat fingers

I thought it was interesting that this app still had no reviews so I downloaded it and tried it myself.
This is a highly acurate tuner. It is a strobe type tuner that gives a visual tool to see what it is that the string is doing. This is superior to conventional tuners because strings don't vibrate at a single note they carry harmonics that can and do confuse electronic tuners. This is not for everyone though. It is complicated and offers too much information. This tuner is better suited for setting precise intonation by an experienced technician than every day tuning.
At $20 I would have liked to have seen alternate temperments and the ability to tune around middle C in those temperments to better tune to a piano. but I guess it is geared toward guitar tuning and guitars are designed to be evenly tempered, other temperments would never work perfectly. still the ability to add harmonic stretch would be nice.
