I've posted about quite a few resources that you can use to help you find the best apps to meet your needs, but haven't yet covered App Classics. It's right up there with the leaders if you're trying to find the all-time most popular high-quality apps. The developers of the site say that they rate apps using a formula that analyzes iTunes rating information to identify and grade truly classic apps. On the front page of the site you'll see the top app classics across all categories. Or you can use a drop-down menu to view apps by category. Each classic app is awarded a gold, silver, or bronze medal depending on how established of a classic they are calculated to be.
