You're likely often looking to find the best apps, and what better measure than those apps that are surging in popularity in the App Store? Hot App Finder (free) alerts you to the apps whose sales have had the highest rate of increase. The information is updated 4 times a day, and you can view the app descriptions and screenshots without leaving Hot App Finder. The app polls App Stores around the world, and ranks the top 100 paid and top 100 free apps in each of the 21 App Store categories.
