ProjectorPro

This is an extremely useful app, but it will freeze when it is in the background. It becomes unresponsive. You have no choice but to kill the process and start over. Projector central's web app is flash only, so mobile users are a little hamstrung. I hope the developers will update the app for 64bit and fix the freezing bug. I gladly would pay more for the app since it is so useful but only if the problems were fixed.

I just purchased this app in full knowledge that it is not 64-bit ready and may soon become obsolete. I already knew that my recently discontinued projector was in their database. The app is very well done, easy to use, with a great visualization of the projector to screen setup. Not to mention it comes from a highly respected forum in the AV community. To be honest, why people complain about $2 for any reasonably functional app is beyond me. As far as I'm concerned, just my single use of this app is well worth the $1.99 purchase and I would have no problem paying for updates to the database. Putting things in perspective, a good app is certainly worth a lot more than a cup of coffee or a beer. As Stan Lee would say, "Nuff said!"

Two points: Have been using this app now for a few years. Have only run into a projector missing from their data base twice now. Both times I emailed the support address, provided the projector model number, and the missing projector was added very quickly. Like, within 24hrs. The most important calculations are included in this app and they are reasonably accurate. This is esp. true of Foot Lamberts or the perceived intensity/brightens of a projected image, keystone, and image size vs. distance. Price is reasonable and their update model seems fair - considering the tool remains free when accessed through a browser.

To start with, the app is poorly designed with no ability to bookmark a projector or even to *search* for a projector. Considering the number of projectors and brands out there, you can imagine how tedious this makes using it. The bad design I could at least live with, but on top of that, many of the of lenses available for various projectors aren’t available, making it actually unusable if you have those lenses. Both projector/lens combinations that I have are not available and one of the projectors is rather common and produced under three different brand names, none of which have the right lens available for use. It’s rare that I post negative reviews, but these issues are so easily fixed and blatantly obvious that I felt I had to. The app should be free if it is this poor.

This is a good app for finding a projector throw distance when you don't have a device that can use flash (like a smart phone). I recommend it!
