FlexiLingo transforms everyday media into a language classroom — without leaving YouTube, Spotify, or BBC.
Install it once. Then watch, listen, and read your way to fluency.
Interactive Subtitles
Every word in the subtitle is clickable. Tap any word to instantly see its translation, definition, pronunciation, and example sentences — in the middle of the video, without interrupting your flow.
CEFR-Color-Coded Vocabulary
Words are automatically color-coded from A1 (beginner) to C2 (advanced), so you always know which words are worth your attention and how your vocabulary is growing.
Phrases, Idioms & Collocations
FlexiLingo doesn't just analyze single words — it detects phrasal verbs, idioms, and fixed expressions, so you learn language the way native speakers actually use it.
Save Words & Review with Spaced Repetition
Save any word or phrase to your personal deck with one click. Then review it using flashcards and a spaced repetition system that schedules reminders at the perfect moment.
AI-Powered Content Analysis
FlexiLingo analyzes the full content of videos and podcasts to surface vocabulary by CEFR level, highlight collocations, detect grammar patterns, and show which words appear most frequently — so you can prioritize smarter.
Works Where You Already Learn
YouTube, Spotify, BBC, News in Levels, SpotlightEnglish — no need to change your habits. FlexiLingo works where you already spend time.
Whether you're preparing for IELTS, learning a new language from scratch, or just trying to understand native speakers better, FlexiLingo is the tool that turns passive watching into active learning.

Smarter Review System
We've completely overhauled the spaced repetition review system to make studying more effective and intuitive.
• Due cards now appear first, sorted by urgency. New cards are introduced at a controlled daily rate based on your learning plan.
• Stale sessions are automatically cleaned up. No more getting stuck on old, unfinished sessions.
• Custom sessions now properly include all deck cards, respecting your cards-per-session setting.
UI Improvements
• When all cards are reviewed for the day, the app shows "All caught up!" with a Custom Session option instead of a confusing error.
• Deck Progress panel now shows your full deck progress — mastered, familiar, learning, and new card counts with a visual progress bar.
• Tapping the Review tab now properly returns to the session list. Session transitions are smoother with no more screen flashing.
Bug Fixes
• Fixed cards repeating in every session instead of following the SRS schedule.
• Fixed Custom Session returning more cards than the selected limit.
• Fixed session completion screen briefly appearing when starting a new review.
• Fixed bottom sheet occasionally not opening on repeated taps.
• Improved error messages with proper translations when no cards are available.
