Hey Product Hunt 👋
I'm Matt, the maker behind EXRENA and the rest of the HabbleTabble universe.
EXRENA started from a frustration I had while learning languages with a friend — every flashcard app we tried trained us in isolation. We'd grind Anki separately, then meet up and have nothing to do with it together. Vocabulary review was a solo chore, not something you could share.
So I built the thing I wanted: open a link, scan a QR code, race each other through 10 words. No accounts, no app store, no setup. Just two phones and a friend across the table.
Honest note about the business model:
EXRENA itself is genuinely free. No limits, no daily caps, no premium tier, no ads, no tracking. The Ko-fi link is there if you want to support the work, but it unlocks nothing.
That said — I'm not pretending this is pure charity. EXRENA is the friendliest entry point to HabbleTabble, a small family of language tools I'm building. The others (like derdieda.com for German articles, with more in the pipeline) share the same philosophy:
• Zero accounts
• Zero subscriptions
• Zero tracking
• Free daily usage, always
• Optional one-time payment for unlimited Pro — pay once, own it forever
If EXRENA earns your trust, maybe one day you'll try the others. That's the whole funnel. No retargeting pixels, no email harvesting, no dark patterns — just "here's a free thing I made, here are my other things if you ever want them."
Would love to hear: what languages are you learning, and who would you play against? Happy to answer anything about the stack, the philosophy, or why I'm allergic to subscriptions 🙃
