Description by Implicit Knowledge, LLC (from the App Store)

Read real books in French faster

DejaLu helps you prepare for a specific book by teaching the vocabulary that appears in that book first. Instead of generic lessons, you train on high-value words tied to the text you actually want to read.

Start with *Le Petit Prince*, complete short review sessions, and build the vocabulary you need to move through the story with more confidence.

Why learners use DejaLu:
- Targeted learning for one real book, not random word lists
- Short, focused review sessions that fit into a busy schedule
- Vocabulary-first approach that makes reading feel less overwhelming

Who it is for:
- French learners who want to start reading authentic books
- Intermediate learners stuck between textbook French and real texts
- Self-learners who want a concrete, motivating goal

If your goal is to actually read in French, DejaLu gives you a practical path from study to story.

Download DejaLu and start preparing for your first real French book today.
