★ FREE, WITH ONE OPTIONAL PURCHASE

All 550 facts, all 550 quiz questions, all 11 themes, your favorites, your trophies and your stats are free — and stay free. A single small banner sits at the bottom of the fact and quiz screens, and that is what pays for the app.

Prefer it gone? One optional one-time purchase, "Remove ads", retires that banner permanently — on this device and on any other device using the same store account. It unlocks no extra content, because there is no extra content to unlock. Nothing is ever locked behind a paywall, and there is no subscription.

★ SIMPLE & FRICTIONLESS

No account. No login. No sign-up. The only optional permission is photo access, and only when you choose to save a fact card as an image.

★ AVAILABLE IN ENGLISH & FRENCH
