BenQ QCast

Want to use Qcast on my IPhone. But massage show "Unable to Download App" Please solve this ASAP.

The concept is great but doesn't work well. I can't get the App to read my keynote presentation so I tried PowerPoint through Google drive. That didn't work so I signed up with Dropbox and finally it worked. I have to make JPEG files and load them to PowerPoint or the app will mess with my layout. It took me 25 tries to get the full presentation, full slides an each slide on their own display screen. I turned of the app to save power, thinking the correct, full presentation would come right up but no. I did one last test run before the meeting and it took me 5 more tries to get it correct. That happened for two separate meetings. This can be a useful tool but don't waste your money on the equipment until these things are fixed.
