Not sure how to set up and design your home theater?

There’s an app for that.

SIM2 says its SIM2Calc app is a handy tool for DIY home theaters. It’s available on Apple’s iTunes store for $29.99.

Although the high-end projector manufacturer designed the app, it doesn’t appear to be exclusive to SIM2 projection theaters.

The company says it’s a comprehensive collection of calculation tools covering the vital aspects of home theater design, which include:

• Screen type and size
• Projector model
• Aspect ratio
• Throw ratio calculator
• Geometry settings
• Viewing angle map
• Luminance levels

Check out how SIM2 says the app will walk you through home theater design:

Simply start by defining the screen size. The Screen tool allows for easy calculation of any screen dimension. Support for any aspect ratio is provided, allowing the user to choose from a selection of widely-used ratios or to define a specific custom setting.

The next step provides the parameters for projector placement based on the Screen Size/Ratio previously entered. Alternatively, the user can enter the distance from the screen and desired projector placement and the tool will calculate the required screen size; this is particularly helpful for selecting the ideal lens type on SIM2’s higher-end projectors.

The Luminance tool determines, based on the above —mentioned parameters, the selected projector model’s light output, using the Screen Gain information and Projector’s factory declared Lumens value.

With the Angle tool, the user can validate that the viewing angle is correct for the intended seating position in accordance with industry standards such as THX or SMPTE.

Offering added flexibility, SIM2Calc works in both imperial and metric units and the Settings tab gives you the choice between centimeters, meters, inches, and feet. It also provides luminance information in both Foot Lambert and Nits.

The Sim2Calc is compatible with iPhone 3G and higher and the latest models of the iPod Touch. SIM2 authorized dealers will receive complimentary downloads.
