Post your idea and I'll build it for free!

Hey IH!
Pasha here, creator of https://less-dev.com
I am looking for some web apps to build with the "less" platform.
Post your idea here and I'll build as many as I can this week.

What you get:
Fully functioning live MVP, all source code.

Requirements:
Web app, something you think can be built in <3 weeks.
Bonus points: good cause.

Small print:
Will be implemented using https://less-dev.com with a small link back
You can continue building it or export out - up to you
