This app is for PROFESSIONAL projectionists.

This app is for PROFESSIONAL protectionists, not the prosumer. All of the projectors are professional projectors you would normally see used in trade shows, concerts, and the like. IE: Christie, Barco, Panasonic, and a few others.

It allows for edge blend calculations, distance calculations, lens calculations, lumix/nit calculations, etc, and will show you a miniature cad visualization of your setup. It's pretty awesome. For the most part, it's automatic, and definitely for the professional projectionist.

I think the reviews are sub-par because most purchases have been from someone expecting a CONSUMER tool and nothing more advanced than a living room setup. Albeit, this app does that too; it just does a lot more.

Thank you, programmer! I'll use this next time I blend!


Great, almost perfect

It's by far my favorite resource and app for most lens calculations. The list of projectors could use some updating. I use an NEC NP-PX750 and a specific short throw lens, which I recently found out exists (NP30ZL), isn't in the list of options in the app. I love how the developer recently added info about a Christie projector I use, which I'm guessing is in response to a review I wrote; it shows they care. Thanks!

Hi, this feature is available in the app. Just press the action button in the top right corner while selecting projectors.

I love the app, would suggest it to any video technician professional. It is a handy TOOL if you are not quick with math. Only thing I wish it had was an interactive projector diagram that you can see your screen size and projector, and move the projector back and forth like on the Christie website .
