Yesterday we saw webOS finally surpass the 5,000 application milestone, and today a couple more mobile platforms have broken significant app barriers.  First up is Windows Phone 7, which has made pretty big gains in app selection despite not even being available for two months.  The folks at WP Central are reporting that WP7 now has over 5,000 apps available to users, although unofficial app counter WP7applist says its tracking only 4,994 apps as of this writing.  The average price of an app on the Windows Marketplace is $1.51 and, of the 5,000 total apps available, around 1,100 are games.

Next up is Android, which reached 100,000 apps back at the tail end of October.  This time, unofficial tracker AndroLib.com is reporting that there are 200,000 bits of software in the Android Market.  Another interesting stat: Android apps have been downloaded over 2.5 billion times.  It's important to note that the last time we saw AndroLib's numbers, they were reporting that there were 100,000 apps when there was actually only around 83,000, so the actual total of Android apps may be just a bit south of 200k. Also, not everything in the Market is an app, as there are plenty of wallpapers, themes, etc.  Still, 200,000 is a pretty impressive number

Android's growth has been well-documented, so it's no surprise that there are a ton of apps available for the platform.  Even gaming, which has often been cited as one of Android's weak points, is showing signs of growth in the Market.  When it comes to Windows Phone 7, it's pretty remarkable that Microsoft's OS has been able to amass 5,000 apps in just about two months.  To compare, webOS has been around for around 18 months and only recently surpassed 5,000 apps.  Regardless of what the platform is, though, one thing is sure: apps are big.
