Curiosity of the Day
Hey HN! I've built Curiosity of the Day to help people increase their knowledge of the world, one day at a time. Each day, it presents the user with a new fact or piece of knowledge about anything from history and science to art and culture. I’d love to get some feedback on ways to make the app better, and any other ideas on how to make learning more fun and engaging.
Curiosity of the Day launched on April 6, 2023 with 26 votes, #1,516 of 4,853 launches that month and more than 75% of that year's launches.

It's designed for people who want to expand their knowledge gradually through daily learning. The app focuses on making information accessible and engaging in bite-sized daily portions.
