Customer Reviews


Look no farther for a windows extended monitor solution. This is a *great* app and works well on wifi or USB. I own them both. My Ipad Pro 12.9 works perfectly. Great resolution options (I like 1280x1024 on my 12.9 pro), great options for using ipad to make a nearly native touch solution for windows! Tremendous value and you can use an older Ipad 1 or 2 too.

Does not work at all

And the support is horrible, basically no support. When I contacted support for help or refund, they force you to provide LOG file but there are no clear instructions on where the log files are created to upload,, basically you cannot contact support without them, hence the most horrible support. Don't waste your money and find something with better reviews.

Annoying, Unnecessary, Requirement

I used to use this app and was going to install on a computer at work where I needed a temporary 2nd monitor. The requirement to have iTunes installed is both annoying and unnecessary. There are many other dual monitor apps out there without this limitation that are much better.
