Frequently asked questions

What is flangu?

Dropdown arrow

flangu is a language-learning app that uses spaced repetition and flashcards to help you retain vocabulary efficiently. Think of it as a combination of Anki and Google Translator. Here's how it works:

1. You can translate words directly within flangu, and they are automatically turned into flashcards. You can also create cards manually.
2. These flashcards are organized into decks based on specific topics or languages, such as "Business English" or "French Idioms."
3. A spaced repetition algorithm determines the best time to review each card. This way, you focus only on the cards you need to, saving time while improving long-term memory.

flangu also provides tools to make language learning even more effective, including:

• Text-to-speech (pronounciation)
• Synonyms and alternative translations
• Dictionary definitions
• Real-life examples
• Romanization


By combining translation, spaced repetition and above tools flangu helps you build you vocabulary faster, remember it longer and learn langauge more effective.
