Expressed - the what and why of it all.

Hey there Product Hunt!

During a video call - I've often found myself thinking: "if only I could just grab a pen and sketch this idea" - that's what Expressed makes really easy - sketch directly onto the desktop, without all the messy networking / joining ceremony.

I'm trying to make it easy (and fast!) to sketch a thought or idea during a video call - in order to arrive at something better, this can help clarify / teach / explain, the way you might grab a piece of paper and a pen in real life. While I've used it for code reviews and trading & support - I can imagine coaches (1:1 chats), math/music teachers, small business owners - would all benefit from the idea.

Expressed is a Windows binary (today, once validated I'll do the Mac version), and has:
- pen / highlighter and eraser tools (plus pinch and zoom)
- a web-based client, so that part works on anything
- records a movie of the strokes, and all your audio (optional), regardless of which video call software you are using
- deploys & updates through the Microsoft store
- an interesting approach to avoiding all the typical networking headaches - connect easily via a QR code.

I'm a developer by trade and really wanted to scratch this itch. I wrote the Windows version first, and now I need to validate further if the idea is useful. I'm looking for the following, in priority order:

1. is it useful / do you like using it - it's free with some minimal limitations - so there is zero barrier to entry here.
2. is the desktop app and web app intuitive?
3. I LOVE critique and constructive feedback - with a goal of validation and making it even more useful.

I must admit - as a founder, I've probably put too much effort into the app before doing extensive validation - if you have an opinion on that, do let me know :-)

If you get this far ready - congrats! I'm validating the product here - there are LOADS of other things the app could do. To name a few: disappearing ink, multiple pages, seeing who is drawing/when, web front end instead of WPF, the list goes on and on... first validation, then expansion.

Have fun, I hope you find it useful - let me know if you do, I need your feedback to know I should carry on!
