About this app

• Manages the memory level of each word
• Selects and studies only the words you need
• Automatically managed review
• Long-term memory retention system

(1) Memory-Building Vocabulary
Words are managed in 5 levels.

New → Blur → Focus → Clear → Vivid

Through learning, words evolve into increasingly clearer memories.

(2) Spaced Repetition System

Vividy automatically calculates the review time for each word.

Day 1 → Day 2 → Day 5 → Day 14

When the review time arrives, a test is generated, and the memory level is adjusted based on the correct answer.

(3) The Most Efficient Learning Algorithm

From a vast number of words, only the words you need to study right now are automatically selected.

It reduces words you already remember well and focuses on words that require review.

Therefore,

✔ You can reduce study time

✔ Increase learning efficiency.

Remember longer.
