PurFact
General knowledge that sticks
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
A few questions a day that actually stick: flashcards, games and duels with friends. Start for free, keep your progress on iPhone, Apple Watch and in the browser.
PurFact is general knowledge for in between: short flashcards on history, geography, science, art, music, sports and much more, with pictures, maps and sounds.
What you already know comes back at growing intervals, what you don't yet comes back sooner. That's how knowledge actually sticks, a few minutes a day are enough.
• Thousands of questions in many knowledge packs
• Learning paths that build up a topic step by step
• Games: flags, geo quiz, sorting, estimating, periodic table, Morse code and more
• Live duels and remote duels with friends, the Arena, leaderboards and badges
• Daily goal, streak and reminders
• Home Screen widget and an Apple Watch app
• German, English, Spanish, French and Italian
• With an account: your progress on all devices, including the browser at purfact.app
PurFact is free to use. PurFact Pro unlocks unlimited new cards and reviews, all learning paths and your own packs: as a subscription (monthly or yearly, also as Duo or Family) or once as Lifetime. Subscriptions renew automatically unless cancelled in your Apple Account settings at least 24 hours before the end of the current period.
