Questions & Answers

As answered by people managing Folengo.
  1. What makes Folengo unique?

    • Explanations in your native language**, not only in English — the interface is available in 26 languages, and the learning material is translated into several of them
    • Real spaced repetition**: every word, phrase and construction has its own review schedule, from 1 day up to 600 days, and moves between "learning" and "known" based on your answers
    • One course, many formats**: vocabulary games, lessons, grammar rules with exercises and graded reading texts with audio
    • Built for German learners in Germany** — including der/die/das article training and topics people need in everyday life
  2. Why should a person choose Folengo over its competitors?

    • All features are currently free
    • You learn German or English from your own language — useful if your English isn't strong enough for apps that explain everything in English
    • Every word you meet in lessons and texts goes into your personal review schedule automatically, so nothing is learned once and forgotten
    • Several game types for the same word (quiz, listening, word building, flashcards), so reviews don't get boring
    • Works on the web, iOS and Android with one account and synced progress
  3. How would you describe the primary audience of Folengo?

    • Immigrants in Germany learning German for daily life, work and integration courses (A1–B1)
    • Speakers of Ukrainian, Russian, Turkish, Arabic, Polish and other languages who prefer explanations in their native language
    • Non-English speakers around the world learning English
    • Self-learners who want a structured course plus spaced repetition in one app
  4. What's the story behind Folengo?

    After moving to Hamburg I went through the German integration course and saw that many people in my group struggled with learning apps: most of them explain German through English, and not everyone speaks English well.

    I'm a software developer, so in 2024 I started building Folengo — a learning app where explanations and translations come in your own language. It is designed, built and maintained by me alone: the backend, the website, the web app and the mobile apps.

  5. Which are the primary technologies used for building Folengo?

    • Backend:** Symfony (PHP), PostgreSQL, Redis, Symfony Messenger
    • Web:** Next.js, React, TypeScript, Tailwind CSS
    • Mobile:** Expo / React Native (iOS and Android)
    • Audio:** AI text-to-speech with a distinct voice for each character
    • Infrastructure:** Docker, S3-compatible storage, Firebase Cloud Messaging, Sentry, GitHub Actions
