Tuner apps for cell phones

[pklima]

I'm old and out of touch when it comes to cell phones... but can you use one as a tuner? I mean, the fancier ones have audio inputs, some processing power and a graphic display, so tuner software should be possible, right?

iPhones have a tuner app you can get.

Cool, I thought this should be possible! I'll see if I can find something for my work phone, then. At least to have as a backup...

I use the Gibson app. It's effective and free.
