I was just looking at MacWorld's AppGuide
and was quite impressed. It's a database of most of the apps in the App Store. The site has reviewed a large number of apps, and for each of Apple’s 20 categories MacWorld lists the apps that it has given the top rating. An interesting facet of the site is that for each of Apple’s app categories, the site breaks that down into 20 subcategories (though at first it gets confusing, since it's easy to think that you looking at the main menu rather than a list of subcategories). The site lets you sort the apps in any category according to rating, user rating, price (low to high), and more. You can also view the apps that are on sale. And you can limit search results to cost (apps less than $1, less than $5, etc.), age restriction, and compatibility (for example, only showing those apps that work with the first generation iPhone). Perhaps the best feature is App Essentials
, which lists the top apps on some 50 specific topics, such as puzzle games, Facebook add-ons, getting a job, racing games, mulitimedia apps, and football.
Apps for Everything
on Apple's website is a new iteration of a site I mentioned previously that lists collections of apps on common subjects, such as Apps for Cooks, Apps for the Great Outdoors, Apps for Work, and Apps for Students. The page currently has a dozen collections. In those cases where the collection overlaps an App Store category, such as Apps for Students overlapping the Education category, then the page for that specific collection also lists the top 10 paid and free apps for that category. Apps for Everything also includes staff picks, which includes a Pick of the Week.
