Five questions a day.
Every answer cited.
A daily habit that leaves you knowing something you did not know this morning — and shows you exactly where it came from.
No account. No ads. Works offline. Nothing to pay, now or later.
A genuine question from the live app — not a mock-up.
Most quiz apps test you. This one teaches you.
Getting it wrong is the interesting part — that is when you learn something. So the answer is never the end of the screen.
Every answer carries its source
One tap takes you to where the fact came from. If we cannot cite it, we do not ask it — which is why the bank grows slower than it could.
The answer opens a door
After each question: the book, the museum, the place, the documentary. Curiosity should lead somewhere, not stop at a score.
History with the whole world in it
Mali, Aksum, Kush and Kilwa alongside Rome and Athens. Written on their own terms, not as footnotes to somewhere else.
What you miss comes back
Questions you got wrong return days later, then weeks later, until you own them. Free spaced repetition, no subscription.
Built for how you actually read
Timers off, dyslexia-friendly text, read-aloud, high contrast, bigger type. All free, all in Settings, no upsell behind any of it.
Works with no signal
On a plane, on the underground, in a dead spot. Install it once and it keeps working without a connection.
What we will never do
Easy to write on a landing page. So it is written into our Charter, in public, where you can hold us to it.
- ✗Never sell your data. We do not collect it. There is no account and no tracker — your progress stays on your own device.
- ✗Never put knowledge behind a paywall. Not a "free tier". Not five-questions-then-pay. All of it, free, permanently.
- ✗Never run ads. Nobody buys their way into what you are told.
- ✓Always show the source. Every single question, one tap away, so you can check us.
- ✓Always say when we are unsure. A corrected question is worth more than a confident wrong one.
Install it in about ten seconds
There is no app store and nothing to download. Qpio is a website that installs itself — which is why it is instant, tiny, and updates on its own.

It works straight away in the browser. You can play the whole thing without installing anything.
Add it to your home screen
iPhone: tap Share, then Add to Home Screen.
Android: tap the menu, then Install app.
Desktop: the install icon in the address bar.
That is it
It opens like any other app, works offline, and keeps your streak on your device.
