Crashes with iOS 6 on iphone4

I have used this app daily for about 2 years. I am a precious metals buyer and relied on this app in my work. I would be willing to pay for this app if the developer would continue to support it. I dont remember now If it was free or not. Its been too long. It seems they have just ditched out on us. A bummer deal for sure. Oh well, moving on!
