A friend of mine recently pointed out that Apple has an RSS feed with the top 300 iPhone apps. This is interesting because iTunes only shows the top 100 apps, and on the iPhone you can only see the top 50 apps. My Graphing Calculator app has been on the top 10 paid apps list since February under the education section, but I had no idea where it stood on the overall list. It turns out my Graphing Calculator is one of the top 300 most popular paid apps for the time being. As I’m writing this blog entry, my app is sitting at #223. I made a quick python script that parses the RSS feed every hour, and makes a simple and easy to read website.
