Just to let you know i tried out your app and it works, but still needs some features to be useful.
Last weekend I installed mint linux on an old acer aspire one mini laptop pc I had lying around and wrote a php script that would poll the btc-e website parse the json and check if it was below or above a certain value. Then ran a cron job every 30 minutes calling the script. If the value was above that set point I would have it text me. I just had it send out an e-mail to my
phonenumber@vtext.com You have to use a legitimate SMTP service, like google's free SMTP service though, or else all your e-mails are filtered out as junk mail. I think that would add some real value to your program and wouldn't be that hard to implement.
What language did you write it in ? C# / Visual Basic? The look of the program reminds me of the VS2008 era apps that I loved so much. (not sarcasm, I actually liked it)
Good work on that first release, if you don't like the e-mail idea, maybe having the app icon flash would help. Right now its no different than staring at the BTC-e site directly.
Good luck.
