Does anyone have an app that lets me draw on the ipad and show it live on my laptop? Is that what astropad and now Sidecar does?

I resorted to joining Zoom meetings twice and sharing the screen with my ipad session as host and drawing in the Notes App

That's a pretty funny/clever hack (took me a minute to figure out you're Zooming with yourself). You can also try AirServer (similar to Reflector). There's a free trial. https://www.airserver.com

I use it mainly for audio streaming from my phone to my MacMini / Stereo, and sometimes to play Alto's Adventure on a projector.

Or, if your Mac is compatible, just try Sidecar. There's a hack to make it work on older Macs, but I think officially it's tied to the ones that have hardware HEVC/h.265 support. http://osxdaily.com/2019/10/11/sidecar-compatible-mac-ipad-l...

Funny name I used to use something called AirParrot by a company called Squirrels

It was for extending my desktop to a chromecast. Not mirroring but extending and acting a second monitor. It broke at OSX 10.13 and I gave them 6 months and stopped trying

Yes, multiple Zoom sessions from my same user account. I'd mostly do this to convey a diagram live with other people, that I would draw out. So They'd join once, I would join on one device and my ipad, with the first device being so they could see me sitting normally during the whole session.

QuickTime can do this, or at least it could before Catalina (I’ve not upgraded so can’t be sure). Just plug the iPad in and use the screen recording feature (you don’t have to actually start the recording — the preview is sufficient).

HMMMMM well worth considering if other options don’t pan out

That's a use case that the app Reflector 3 handles. It's sort of the inverse of Sidecar. Lets your Mac display you iPad, iPhone, or Android device live in OSX over WiFi, by implementing a desktop receiver for the Apple AirPlay and Google Cast protocols.

Astropad does this, yes. https://astropad.com

Luna Display does exactly that - just mirror your display to your iPad and anything you do on your iPad shows on your Mac display too. Best thing about Luna is it gets you Pencil support on the Mac. People have been ditching Wacom tablets since the iPad has dramatically better (lower) latency.

Love my Luna - even with sidecar I still see me using Luna. Hope they survive :(

So sidecar doesn't (yet, at least) fully do everything Luna does? I guess it probably will eventually..

Apple pencil latency on ipad OS is crazy low and I hear it was already lower than a typical wacom tablet, so this is quite compelling. Sad for Astropad that Apple are taking their business away, but it is a logical step really... :/

I’m using Screen Mirroring by 2kit[0] to stream from my iPhone to a Linux laptop. It makes a MJPEG stream on local network, and I’m using some custom CSS for their website to fix scaling. It has an iPad version, so you may want to test it.

That's more of the inverse. I think an AirPlay receiver on your Mac might work, but I'm not sure. Sidecar, Duet Display and Astropad let you draw on your iPad as a secondary display for your Mac, using Mac apps.

Sidecar with mirroring turned on if you want both screens to show the laptop, Airserver with Airplay from the iPad if you want both screens to show the iPad.
