Pros
No pros at all.
Cons
I managed to get past the opening screen which wants you to buy a key from their defunct website, at which point the program immediately stopped responding. It didn't open even once. Plus you've got to download two other extra programs that gave me pop-up ads. Seriously disappointed.
Summary
Awful, unresponsive, virus carrier.
Crashes on startup.

Very accurate (1/10 cent). Thank you!!!

The center of the interface display appears transparent upon initial opening of program. Works perfectly after minimizing and then returning to normal size.

Pros
there were no pros that i could find
Cons
couldn't use, kept crashing tried to trick me into installing some toolbar, i HATE that! then begs me to register although i can try it free for ever.
Summary
dont install
Thoroughly Confusing and Ineffective
JonathanShanghaiApril 10, 2011
Pros
I guess if you are a computer nerd with a PHD then all the dials and settings may mean something to you. If you want to just tune your guitar this is NOT the product for you.
Cons
Broke my string using this. I just want a light that goes green if I get it right. Tis just shows the note you play and gives no guidance on how to correct it. I tried for a LONG time to get an E2 but it just kept reporting other notes with no help.
Summary
Overly techy underly helpful.
THIS IS NOT FREE
ZenFerretMarch 23, 2011
Pros
None. This app is mislabeled and crashes under anything above Windows 95.
Cons
There is no trail. THIS APP COSTS $35. Also, it will not run under Windows 7 or Vista.
