If you own an iPhone or iPod Touch (or maybe if you’ve pre-ordered an iPad), and you work in Stereo Video, then the RealD people have released the App you need to get.
The RealD Professional Stereo3D™ Calculator for iPod® and iTouch® provides a learning and production tool for filming in stereoscopic 3D. Whether you’re a seasoned stereographer or relatively new to shooting in 3D, this easy-to-use stereo calculator will help determine the right setup for your rig, fully taking into account parallax, separation, camera and lens choices, all from the palm of your hand. The RealD Professional Stereo3D™ Calculator can help reduce production time by reporting how subjects will appear in 3D, while maximizing on-set efficiency, particularly with new shots setup on-the-fly.
Now, All this awesomeness doesn’t come cheap, currently going for $299.99 ( 
), but it’s a huge amount of functionality that includes everything you need to get your screen, rig, and camera settings ready to go.
