Show HN: Next MacRuby app in App Store

Hello, I want introduce to HN community my application which built on MacRuby 0.10. Application called Debt Reduction Manager. As experienced Objective-C developer, I though that MacRuby is for play only but have found that its great framework for build apps for Mac, much easy then I wrote obj-c code and same time work perfect(even not final version) with cocoa.
