TortoLingua: Learn by Reading

mriabchenko

About this app

Learn a language by reading texts that match what you understand.

TortoLingua turns reading into adaptive practice. Choose a language, read a short level-matched text, and select unfamiliar words or sentences for contextual translations. What you mark helps future texts stay close to your level and bring difficult vocabulary back in meaningful context.

Why TortoLingua:
- Read short, level-matched texts
- Translate words and sentences without leaving the reader
- Listen to words and texts with audio
- Meet difficult vocabulary again in later reading
- Upload private TXT, EPUB, or MOBI books and resume where you stopped
- Practice writing systems with script and alphabet support
- Learn across multiple languages from one account

Available learning tracks include English, Spanish, French, German, Polish, Ukrainian, Serbian, Japanese, Korean, Brazilian Portuguese, and European Portuguese.

No streak pressure or leaderboards—just calm, focused reading that becomes more understandable over time.

Every learning feature is free. There are no subscriptions, paid tiers, in-app purchases, or ads.

What’s new

Korean is now available for learning and as an app language.
