About this app

📚 Learn words from the content you actually enjoy.
FluentBoo: Vocabulary Builder helps you capture, understand, practice, and remember vocabulary from your own content instead of memorizing random word lists.

Whenever you discover a useful word, phrase, quote, sentence, or expression, FluentBoo helps you save it quickly, learn it in context, and review it through powerful learn and test modes.

⚡ Quick Add Vocabulary
With Quick Add from notifications, you can add new words without breaking your flow. While reading, studying, watching videos, listening to content, chatting, or browsing, you can save vocabulary fast and turn everyday moments into long-term language growth.

No more losing useful words in screenshots, random notes, translations, or browser tabs.
