I first spotted LensBoost during a Hackathon at BlackBerry DevCon. Mblware was working on the promising WebWorks Instagram-like app for awhile and perfecting all the kinks. The app lets you filter your photos adding some slick effects and then share them over Twitter, Facebook, and BBM. Its a pretty impressive app and even does tilt-shift with relative ease. The only thing missing is a faster processing engine/library or tweaks but we can hope that comes with future updates!
You can pick up LensBoost in App World for $1.99
