The Windows Phone 7 Marketplace now has more than 5,000 apps, according to WP7applist.

As of Wednesday morning, the site was tracking 5,099 apps in the marketplace. About 28 percent of them were free apps; the average price was $2.31. WP7applist found that 113 apps were updated every day, on average. In the last 24 hours, Microsoft added 85 apps and 135 apps were updated.

The Windows Phone 7 Marketplace has seen a steady increase in the number of apps in the last two weeks, from about 4,200 on December 16 to just over 5,000 by December 28, according to a chart on WP7applist.

Microsoft has not confirmed these numbers. On December 21, the company said its app marketplace had 4,000 apps - the same day it announced that it had sold 1.5 million Windows Phone 7 devices.

In late October, about three weeks after it opened, the marketplace hit 1,000 apps.
