The independent 3rd party Android market, AppBrain, added some interesting metrics to their lineup of stat info that you can access on their site.  If you are a developer that has an app on AppBrain, you already know about their pretty impressive developer dashboard that gives you all kinds of information goodies about users that download your apps, as well as the ability to have your app promoted if it fits the criteria.  In addition to that, AppBrain has added the ability to view some new Market statistics.

The new stats allows you to filter the 150,000 available apps on the Android Market and AppBrain into different categories, including the ability to see “low quality” apps.  This can certainly be useful to gauge how crowded an app category could be before you jump into the work.

Check out the new info and let us know what you think.
