I love the explosion in whiteboard collaborative tools, but I am so frustrated how none of them support pressure sensitive styluses. Pressure sensitivity is extremely important for a natural writing experience and creation of good diagrams while giving lessons with such tools. Regrettably, even browser support for the required (standard) pointer event APIs is really buggy, so one needs to use native apps for now.

95% of whiteboard apps I've used have unreasonable latency.

I'm not talking about network latency, but in the browser, on my end. If the drawing is 300ms behind the cursor, handwriting is wonky.

Microsoft got this right in their early Surface stuff, but somehow messed it up in Teams. Google does this wrong. Zoom does this wrong. There are a few things which does this well, but it's rare.

Teams is electron, so you're still in the browser and an abstraction from the hardware.

LYNX Whiteboard does pressure and with the 7.4 release later this year it will add an ink bleed effect. The question is if your hardware supports pressure data.

Disclosure, I work on the project.

I have some questions that the site doesn't seem to answer:

Does this do live audio and video, or do you use something like Zoom alongside it?

Can students write with a finger on a phone?

Can students log in to the same session multiple times, e.g. phone to write, computer to view on a bigger screen?

It seems to be free at the moment, so what's the business model?

Do teachers have classroom management features like muting and kicking out?

Is it possible to type as well as write? Is it possible to type maths?

I have no idea what this is from that webpage

Wow, there is just no information at all about it. A few clicks leads to the user manual, which also assumes you know what it is: https://download.saharasupport.com/Documents/LynxHowToGuide..... There's a little more information on the app stores, mostly hidden in the loud video: https://play.google.com/store/apps/details?id=com.clevertouc..., https://www.microsoft.com/en-us/p/lynx-whiteboard/9np33m4m3r.... It seems to be mainly focused on lesson planning and classroom use.

Got to plug Concepts app. Pressure sensitivity included. Multiplatform. And opposed to MS Whiteboard, you can save your work in your own disc and sync it with whatever tool you want. It has been a game changer for me. No collaboration though.
