Try to remember the word first. Reveal the card. Read the example when you need context. Then choose Learn or Know.

ENRURO doesn't try to replace your memory with an AI tutor. The effort is part of the training.

Set a daily goal of 10, 20, 30, or 40 cards. ENRURO’s built-in CEFR-aware scheduler builds each session around the vocabulary still in your training pool.

ENRURO treats vocabulary like a workout instead of a linear course.

A1–A2 cards warm you up, B1–B2 provide the working load, and C1–C2 bring the heavier vocabulary. 

A built-in CEFR-aware scheduler mixes these levels into the training flow instead of making you complete one textbook chapter after another. 

Your Learn/Know decisions gradually shape the deck around what you still need to learn. 

ENRURO is designed for people who already know some basic grammar or can read in a language and want to expand their vocabulary through focused recall practice.

It may be a good fit if you:

• want to expand your vocabulary in a language you're learning; 

• study more than one language;

• want vocabulary flashcards with examples;

• need an app that works offline;

• prefer a simple tool without accounts, ads or constant notifications;

• want to practice remembering instead of asking an AI tutor for the answer.
