StumbleUpon relaunched and redesigned its iPad application back in mid-July, and today it has unveiled a new experience customized for Android Honeycomb tablets. The newly designed UI is much more tablet-friendly of course, but it's also been optimized for faster and smoother loading. 

The new version also brings some new features, such as the Explore box which was previously only available on the web version of StumbleUpon, and swipe to stumble, which involves (unsurprisingly) a swiping to left or right gesture to find new content. 

The new version is available in the Android Market right now.
