Choose Duolingo when
- You are starting from zero and want the app to sequence the basics.
- Your biggest risk is not showing up consistently.
- You prefer short, varied exercises across several skills.
- You need a language outside LitBook's current six.
- You want supported Max experiences such as Video Call and Roleplay.
Choose LitBook when
- You can read short sentences and want sustained comprehension.
- You want adult-interest topics at a chosen CEFR level.
- You want questions that reveal whether you understood the passage.
- You want missed words to return in later reading contexts.
Where LitBook is weaker
- It is not a complete course from the first alphabet or greeting.
- It has no leagues, XP economy or equivalent social habit system.
- It does not offer a broad speaking curriculum or live conversation partner.
- Its six-language scope is far narrower.
Where Duolingo can run thin for readers
Duolingo's compact core loop makes practice easy to start, but short matching and translation exercises do not always train the attention needed to hold meaning across paragraphs. Stories and advanced experiences add context; learners whose goal is books, news or long-form web reading may still need a separate extensive-reading habit.
A seven-step combined routine
- Use Duolingo to establish a daily cue and cover unfamiliar basics.
- Take LitBook's level test once you can understand short sentences.
- Generate a short passage on a familiar topic two or three times per week.
- Read once without lookup; answer from memory.
- Review errors and reread the passage with audio.
- Let missed vocabulary return in a later lesson.
- Judge progress by what you understand—not only streak length or XP.
Final verdict
Duolingo is the stronger all-purpose starting system and habit engine. LitBook is the more focused tool for turning that foundation into sustained reading comprehension. Compare LitBook with LingQ, Readlang, or the full reading-app roundup.
