Ratings and Reviews
Works a treat!
I’ve had experience with hardware meant to provide an extra display over a usb cable and for mac this has provided everything that other hardware had promised and more. it even had auto rotation down perfectly unlike the other monitor i purchased. I suspect the lightning cable makes this faster than my usb monitor, but be aware of what is happening when you use these softwares. This has done a miraculous job efficiency wise, but be aware and be kind to your computer and software devs, most macs have one onboard graphics processor, a lot of the time it’s intel onboard. Don’t expect something like this to approach the speed of a thunderbolt connection or hdmi to dvi or vga etc..
All of that said, if you need an extra display for web browsing, or a way to write on your computer while using your ipad as the word processing screen while watching a movie on your regular monitor then this is your ticket.
One of my favorite features of this software is that it gives me access to the touchbar features that are on the newest MacBooks. My work computer is a mac mini 2012 i7 with maxed ram and a boot ssd. It’s not the newest or fastest computer but she still runs beautifully, so i'm attached.. anyhow.. this is perfect.. cake.. also ate.
Sooooo slow with updates
I use a windows 10 laptop along with an iPad Air 2. I’ve had issues with duet display disconnecting frequently while watching videos or surfing the web while using this app, but I just assumed that was due to my slow laptop.
Fast forward to early Nov 2017, I got a new laptop with top of the line specs. It worked fine for a few days and then my laptop automatically installed the Creators update. After that, the app just got stuck in “Launching” for the longest time. I emailed tech support and they had me do all these silly things, and after all that they told me, “oh by the way, unfortunately our app is having some issues with the Creators update and so it won’t run right now. We are expecting a fix in a week.”
First off, shouldn’t that have been the first thing to ask me instead of having me waste my time collecting “analytics” for the app? And then, to make matters worse, it has been over 2 weeks since the rep told me the fix would roll out in a week. I looked up when the Creators update was first released, and it has been almost 2 months! Does this mean that their engineers have been working diligently for 2 months on this and they still don’t have a fix? Either they are really incompetent or they just don’t care about their Windows 10 customers. Until they become more responsive with their Windows 10 updates, I would stay away from this app, for those of you not using an apple computer.
Developer Response ,
So sorry for your trouble, we're working as fast as possible to fix the current issue with the latest Windows Creator update. We will be releasing a solid fix soon.
Maybe with the iPad Pro 12" and a relatively small Mac but...
I have an iPad Pro 10.5 and when matched with my 27" iMac, the screen size and resolution on my iPad makes the interface so small as to be nearly useless. I can see how this app's pro version would be useful when matching a 12" iPad Pro model with a MacBook given the relative similarities in size. I was hopeful that I would be able to use my iPad Pro and Pencil as a suitable tablet substitute with my iMac but that doesn't seem to be the case. Also, given the relative high horsepower of both my iMac and my iPad, there seems to be a significant amount of lag which makes interactions a bit too problematic. There's far more lag than one would expect using devices that have as much processing horsepower as both of these devices have especially with a direct USB connection.
Update: Having just tried to use the Pro version, the screen size issue remains. While it is possible to pinch-zoom on the drawing in SketchBook, the tool panes remain tiny unlike Astropad, which not only zooms the drawing, it also zooms the tool panes as well. There is very significant and problematic lag as well. Gesture inputs from the iPad result in late and very jerky responses in my iMac. Given that this is a wired connection, the lag issue is inexcusable. In short, the app needs a great deal of work and improvement.
