I hope you don't mind if I do a little advertising for my husband and ultimately our family. My husband has been building an iPhone App business for over a year. Most of the apps that he's built have been for clients but just today he put out his first game! We're really excited and have high hopes for it. The game is called MatchTunes. It's basically a game of memory but instead of matching pictures you match music clips that come from your own iTunes library. You can match the same clip or different clips from the same song depending on the settings you choose. For more advanced levels of play you can also match songs that are on the same album or songs by the same artist. We've played it many times in testing and it really is fun, especially the two player mode. If you have an iPhone or iPod Touch, I hope you'll check it out. You can get to it by going through the link from the company website to iTunes or just search for "MatchTunes" in the App Store from your iPhone or iPod Touch.
Here are a few screen shots:
It really is fun. I hope you'll check it out.
