Curioza
Facts that connect
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
You'll end up somewhere you didn't expect. Start on Venus, end on octopus hearts, seven questions later, and never once feel the subject change.
Why is Venus hotter than Mercury? Why does copper wiring beat silver? Why does an electric eel work at all? Most quiz apps would give you three unrelated questions. Curioza gives you one thread, because the answer to the second question is half the reason for the third.
THREADS, NOT LISTS
Every question in Curioza is connected to others by the ideas inside it. Ask about heat, and you're one step from asking about conductors, then wiring, then electric fish, then how a fish's shock even works. A thread is a walk across those connections: seven questions, six subjects, and a reason for every single jump.
You'll start on a planet and end on an octopus's heart, and you'll be able to explain exactly how you got there.
YOUR OWN SKY
Every question you've answered lights up on your map. Answer two connected facts and a line is drawn between them. Come back in a month and your sky is a web of everything you've learned, not a bar chart of how many minutes you spent open, but a picture of what's actually in your head.
BUILT TO BE UNDERSTOOD, NOT MEMORIZED
Every question comes with an explanation of why the answer is what it is, and a "did you know" fact worth repeating to someone else. Get it wrong and you still walk away knowing something. Curioza tracks what you're shaky on and brings it back right before you'd forget it.
SIX WAYS TO ANSWER
Multiple choice, true or false, picture choice, higher-or-lower, a slider for "how close can you get," and put-these-in-order. Difficulty adjusts to you automatically.
A MINUTE, OR AN HOUR
Speed Round: sixty seconds, as many as you can answer, explanations afterward. Daily Thread: the same walk every player takes today, so a score means something. Or just follow wherever your own thread takes you.
Curioza is free to start, with real subjects, real threads, and a review deck from day one. Curioza+ opens every subject, which means threads that reach further before they run out of room to walk.
1,400+ questions across space, the human body, animals, science, geography, history, technology, psychology, earth, food, money, the arts, sports, and the stuff that's just plain weird. Built by one person, not licensed from a template.
