Everything You Need to Learn
Every feature in LumenLingo is based on how your brain actually learns. Timed reviews, background sounds, and study tools that work together.
Flashcards
LumenLingo flashcards look and feel different from other apps. Each card has a smooth, layered design that responds to your touch. Swipe right for correct, left for incorrect, and watch the card animate naturally.
Cards show both languages with pronunciation guides, and colour coding helps your memory through visual cues. The design adapts to dark and light modes.
Every tap and swipe gives you clear feedback. The card flips with a smooth 3D rotation. Borders flash green for 'Got It' and red for 'Still Learning'. Sound plays with each gesture, and you earn 10 points per correct answer.
- Swipe gestures with smooth, natural animations
- 3D card flip with layered design
- Instant colour-coded feedback on every answer
- Pronunciation guides for non-Latin scripts
- Visual and audio feedback on every action
- Customisable deck sizes per tier (50–unlimited)
Timed Reviews
LumenLingo tracks how well you know each word and shows you the ones you need to practise most. Words you get wrong come back more often. Words you have learned appear less.
Vocabulary is sorted into categories — Greetings, Food, Travel, Business, and more. You can see how many words you have learned in each category with clear progress bars.
The system adjusts in real time. Miss a card after a long break? It comes back sooner. Get five in a row? That word joins your learned set. The app works with your brain, not against it.
- Per-category progress tracking
- Learned word sets that grow with you
- Accuracy and streak statistics
- Real-time difficulty adjustment
- Visual progress bars per topic
- Points system: 10 per Flash Card, 10 per Quiz, 15 per Word Builder
3 Distinct Practice Modes
Different practice styles keep things interesting. LumenLingo has three modes that each test a different skill, so your sessions never feel the same.
Flash Cards build speed with smooth 3D flip animations. Grammar Challenge tests your understanding with A/B/C/D questions and explanations that show why an answer is right. Word Builder asks you to spell words letter by letter, helping with spelling and recall at the same time.
Each mode has three levels — Beginner, Intermediate, and Advanced — unlocked as you move up tiers. If you pause for too long, gentle hints keep you going.
- Flash Cards: 3D flip with swipe gestures
- Grammar Challenge: A/B/C/D with explanations
- Word Builder: letter-by-letter construction, 15 XP
- Three difficulty levels per mode
- Progress tracked independently per mode
- Idle hints to keep you in flow
12 Background Sounds
Set the mood for studying with 12 background sounds in four categories: Cozy, Nature, Atmospheric, and Travel. Each one is a layered mix of sounds designed to help you focus and block out distractions.
Study in a Parisian cafe with gentle conversation and clinking cups. Or drift into deep focus with the hum of a space station. Every sound mix sits quietly under your learning so it helps without getting in the way.
Research shows that consistent background audio helps your brain connect sounds with what you are learning. When you study with the same background, recall gets easier over time.
- Cozy: Paris Café, Rainy Window, Midnight Jazz Piano
- Nature: Mountain Campfire, Japanese Bamboo Forest, Amazon Rainforest
- Atmospheric: Observatory Night, Desert Night Sky, Deep Space Drift
- Travel: Dominican Beach, Tokyo Night Street, Venice Canal Morning
- Volume balancing with system audio
- Tier-gated access (0 free → 1 Pro → 8 Elite → 12 Royal)
Breathing Exercises & Visual Backgrounds
LumenLingo is the only language app with built-in relaxation. Breathing exercises show a calming, animated circle that gently grows and shrinks. This creates a relaxed mood that reduces study stress and helps you focus.
Choose from 6 colour themes, each inspired by a real city. Beyond breathing, try Flowing Light scenes with gentle moving shapes, or Space-Themed presets with slow-moving cosmic animations.
These are not just for looks. Research shows that calming visuals lower stress and help you focus. Every background in LumenLingo is designed with this in mind.
- 6 city-inspired breathing exercise colour themes
- 6 Flowing Light scenes (Elite+)
- 6 Space-Themed presets (Elite+)
- Smooth real-time animations
- Respects reduced-motion preferences
- More backgrounds unlock as you upgrade
Progress & Analytics
LumenLingo turns your progress into something you can see. A points system rewards regular practice — earn points for every correct answer, streak bonuses for studying every day, and multipliers based on your plan.
Track your results across all three practice modes: accuracy rates, speed, favourite categories, and streaks. Clean charts make your data easy to read at a glance.
Daily goals keep you on track. Set a practice time or card count, and watch your daily ring fill as you learn. Monthly reports (Elite and Royal tiers) break down your growth by language pair and level.
- Points system with tier-based multipliers (1x–2x)
- Streak tracking with daily goals
- Per-mode accuracy and speed stats
