Hi Product Hunt 👋 I build small mobile apps solo, and this one started with a question I couldn't answer: I drink coffee every single day, and I know almost nothing about it. The fun part turned out to be how much of what "everyone knows" about coffee is wrong. "Coffee is the second most traded commodity after oil" — no source holds up. "Americano was invented by GIs watering down espresso" — same. I ended up keeping a list of 60 claims I had to throw out, and that list shaped the app more than anything else. What's inside: • Three difficulty levels, three choices per question • Every question has a written explanation with a source behind it • A round is 5 questions, framed as brewing one cup: select → roast → grind → brew → serve • 16 languages — the questions themselves are translated, not just the UI • Works fully offline. No account, no login, nothing to sign up for A few facts that made the cut: ☕ A kilo of Panamanian Geisha sold for $30,204 at a 2025 auction ☕ The world's first webcam existed to watch a coffee pot in a Cambridge lab ☕ Lloyd's of London and the London Stock Exchange both started in coffee houses ☕ One fungus in 1869 is the reason Sri Lanka is a tea country today It's deliberately not a barista textbook. If you finish a round with one thing you want to tell someone tomorrow, it did its job. The app is free with ads. Happy to answer anything — and if you know a coffee "fact" you've always suspected was made up, I'd genuinely like to hear it.
