I just got a new iPod and downloaded the iStoboSoft app from Peterson. I've played with it all but an hour or so.
It says you can calibrate the tuner to a known pitch. I have mine at A443 now. What could you use as a known pitch for A443?
I think IStroboSoft is already calibrated pretty well using A443 when compared to my guitar tuned with another electronic tuner.
One thing that this new toy really reveals is that I got a bunch of harps with a lot of out of tune holes. Be nice to get them in tune with themselves and my guitar.
I ordered the Richard Sleigh tuning kit which should be here any day.

I was at my bro in law's when he was having his piano tuned. The tuner used a mega expensive piece of kit. The StroboSift was out by a little, but that was probably due to the iPhone mic.
I think you can get an external mic which improves things.
Incidentally, the piano tuner went green when I told him it only costs pocket change.

The built in mic on the iPod touch actually seems pretty good. It has a Hi-def digital camera as well that I tried using for recording some harp playing vids. The sound was decent and you could upload it right into YouTube if you wanted to.

You don't need an input sound at 440. Give it a 440hz synth sine wave. Whatever you adjust later (concert pitch 440-450) does not affect the calibration.
Your calibration is a fix for microphone errors.

@Jim I found some free sine wave tone generators on line but didn't download anything. But I think you are saying that it if I'm using the built in iPod mic and that mic is pretty accurate, that the software is most likely already calibrated to 440 and adjusting the concert pitch up to 443 won't effect that calibration? The software default did say that it was calibrated to 440 but I changed that number thinking that was what I should do so it matched the 443 pitch I put in where it asks what concert pitch you want to use. I didn't have any known analog pitch so I didn't actually press the calibration button.
