A significant update for my app Picture Effects is now available on the App Store. Improvements include:

• iOS 4 multitasking support and high-res graphics for the retina display (finally! Sorry it took me so long).
• Better rendering performance, especially on the iPad.
• Built-in sharing to Facebook and Twitter (using the ShareKit library).
• German localization.

Picture Effects 1.1 requires iOS 3.2 or higher. The price is $2.99.
