Curio
Learn one big idea a day, and actually remember it
Most of what you learn is gone within a week. Curio gives you one real idea a day, like why the Moon changes shape or why sequels disappoint, taught in a few minutes with visual cards and questions that make you think. Then it brings each idea back right before you'd forget it, with a new question each time, until it's locked in. 254 hand-written ideas across 16 topics, in paths that unlock chapter by chapter. Free on iPhone, no ads, no account.
Hey Product Hunt 👋 I'm Sami, and I built Curio.
I built it for one feeling: being the person in the room who actually gets it. Knowing why a 1% fee can quietly eat a quarter of your savings. Why coffee doesn't really give you energy. Why a pill that "halves your risk" might barely change it. Small ideas that make everyday decisions easier and conversations more fun.
The catch: we read this stuff and forget it by Friday. Reading more wasn't the fix. Remembering was.
So Curio does two things:
1. One idea a day, taught in a few minutes with visual cards and questions that make you think.
2. It brings each idea back right before you'd forget it (FSRS spaced repetition), with a new question every time, until it's locked in.
Gand-written ideas across 16 topics, from money and health to space and persuasion. Free, no ads, no account, works offline. Curio Plus is optional: three ideas a day plus Ask Curio.
I'd love your honest take: which topic should I write next, and did your first lesson make you want a second one?
