I was anticipating function similar (not identical) to sidecar; another functional screen. That's more my fault for not reading carefullly enough, I suppose. Anyway, it worked perfectly the first time I tried it, which is a nice surprise after reading the reviews. (For everyone having trouble I wonder if they granted permission to the app to record the screen; failing to do so would definitely make for "Doesn't work/nothing but a blank screen" results.This doesn't give you another usable screen: Just a (slightly delayed) mirrored display inside a browser window. You could set the browser to full screen and have a non-functional, mirror display on your phone/tablet. If that's something that would be useful to you, this is a great free solution.

Installed the app because it says it offers a free version, but the second you open it up, you're quickly greeted with the fact that it's only for 60 seconds and then you have to pay for the premium app. That's really borderline bait and switch, shame on the dev. This shouldn't be listed as a free app but of course the dev has figured out how to get around that and then strong arm people into paying for the premium version as soon as they have your app on your computer. 60 seconds is definitely not enough time for a user to decide if the app is complete junk, but the dev likely knows this and so wants you to drop your money right away so that once you figure out that you're unhappy with it, it's too late, you've already paid your money. There are a lot of really amazing apps out there on the app store that don't pull this kind of game, this is not one of them. Will 100% NOT recommend.

Why is it I used to have access to screen mirror and now Apple has decided after all this time to make it a Premium Subscription based item. That shouldn't be something paid for especially at such a high price, but even at that it shouldn't require payment at all when it was already previously provided for free and it seems to have come out with one of the most recent updates. I get some of the other Premuim benefit maybe costing a little, but the screen mirroring between your own devices...?

Installed this app because it popped up when I searched Duet Display. I didn't realize it was not the same and App listing said it was free. When I tried it - it was only 60 seconds (though you can retry) and then tells you there is a need to pay for the Premium app. All it did was display my screen on my main monitor multiple times instead of sending to display. Spent time troubleshooting with no success. The issue may be that I was trying to send to an iPhone and perhaps it only works with iPad.
