Troika Labs has released Vectorscope for the iPad. They describe it as  the perfect tool to analyze your stereo material. A spokesperson told us, "Whether you are a producer, mixer, recording artist, or student, we believe that Vectorscope will soon become an indispensable tool for all your stereo audio needs!"

Vectorscope accepts audio coming either from an external iOS-compatible audio device or from an Audiobus-compatible app. Troika Labs says that choosing one mode or the other couldn't be easier: When the app is connected to Audiobus, the audio will be routed automatically thru it, otherwise the chosen audio source will be external.
