Show HN: Scribble/write on your desktop, with any phone/tablet

John from Effective Flow has launched Expressed, a Microsoft Store app that lets users draw on their desktop using any phone or tablet, with the desktop projected onto the device for real-time scribbling. The app, developed part-time over 7 months, uses secure relays and QR code pairing, and is available at https://apps.microsoft.com/detail/9N694D0PN6GB.

Scribble/write on your desktop, with any phone/tablet - I'd like your feedback.

Expressed is a way to make it easy to draw directly on your desktop using any phone or tablet - think along the lines of "I want to draw (on my screen) to help aid my discussion". The desktop is projected onto the phone/tablet, so you can actually see what you're about to scribble over - pinch/zoom and various tools provide the typical/expected drawing tools - and whatever you scribble is seen on the desktop.

If you wanted to try (link to m/soft store): https://apps.microsoft.com/detail/9N694D0PN6GB?cid=hn01 I've often wanted to scribble in code reviews, brainstorming/ideation - so figured, now that AI makes coding a little easier (cough cough); I'll turn that idea into a product.

It took me (part time) about 7 months from initial idea, through validation, writing the product, loads of wrong turns (there are monsters in some of those branches, branches? heck that's a FOREST), etc etc to get where it is today - typical story of development I suppose.

Networking isn't an issue - cos everything runs via secure relays; scan a QR code on a tablet to join.

I'm open to feedback, critique & questions - I'd love it if you let me know if you tried it, found it useful, it crashed or you were surprised by something - I can be reached at john@effective-flow.com or Discord (https://discord.gg/5MJbjzGQa)
