StumbleUpon is a popular service for discovering new sites on both computers and smartphones. Hence, StumbleUpon has released an App Discovery feature for Android OS, so let's see how it works in actions.

As for this feature, you'll get it right from the StumbleUpon app once it updates, and the only thing you'll need to do is to log in with your StumbleUpon account and you're good to go. After you log in, the app will ask you to scan your phone for existing apps, and after that, you'll get the complete list of recommended applications along with descriptions, screenshots, and Android Market star ratings, so you can vote right from the app.

However, this app isn't using your current topics from your StumbleUpon account. We're hoping this will be changed in future. In addition, this feature comes with unresponsive UI. But with tiny touchscreen buttons, it really makes the usage a lot harder than it should be.

As for the App Discovery, it's available on Android Market right now.
