Long story short, I wrote some code, did some mining, and ended up crawling the entire US iTunes App Store, and from this I have compiled some statistics.

Let’s start with some ground stats:

• There are currently 57,292 applications active in the iTunes App Store
• Of this 23,564 are games, leaving 33,728 other applications
• Average price across the store: $2.18
• Average price for games: $1.36
• Average price for other applications: $2.76

Broken down into categories, this is what the distribution of games looks like:

And other types of applications broken down into categories:

You can then break down each application in pricing segments:

And finally, below is the growth rate since the App Store opened considering applications that are still active and available:

For those more statistically minded than me, I’ve uploaded some of these stats to a Google spreadsheet, and if you’re interested in something not included in that, leave a comment and I’ll see if I can add to it.

While the other contributors and I don’t have a problem with derivative works (the code is released under the GPLv2 license), we would appreciate it if you instead thought about contributing back into the project. If you would like to contribute code, make a wiki page or contact me to become a member of the project so you can check-in using SVN. If you do choose to use some of the code in your own projects, please provide prominent attribution and a link back to the Google Code page and/or the web version of the script.

The code is pretty hideous at the moment, and there are quite a few bugs to work out, but please bear with us – we will be making enhancements and bug fixes very soon.

Statistics include:

• Tweets per hour of the day
• Total Tweets per day of the week
• Total Tweets per day of the month
• Top @replies
• Top overall @s

Please keep in mind that there are probably a lot of bugs in it, and it can take a very long time to process if you have a large timeline. Other than that, enjoy!
