LEARN LANGUAGES THE FAST WAY - THROUGH VIDEOS! (Now with Mandarin Chinese support!) ◆ Learn Japanese and Mandarin Chinese through the content you already love. ◆ Gravity is an immersion-first language app that turns real videos and music into personalized learning. Doomscroll short native clips, sing along in Karaoke Mode, or pick something from a hand-curated library of native videos, each one transcribed word by word and levelled for learners. ◆ Whether you're into anime, J-pop, C-dramas, music, or YouTube creators, Gravity helps you build real language skills through context instead of generic textbook lessons. WHY CHOOSE GRAVITY? → Doomscroll to fluency: Moments turns scrolling into learning with a feed of short clips from native content. → Curated video library: native videos across anime, music, entertainment, creators, and more, levelled from complete beginner to advanced. → Word-synced transcripts: follow along word by word as the audio plays, with an English translation for every line that you can show or hide. → Karaoke Mode: follow the lyrics of songs you love, understand every line, and pick up vocabulary through music. → Tap to learn: tap any word for its reading, meaning, and an AI explanation, then save it in one tap. → Context-based flashcards: every saved word keeps the moment it came from, so you can replay the original clip while you review. → Smart spaced repetition: reviews are scheduled so each word comes back right before you'd forget it. → Practice right after watching: review the words you just saved as soon as you finish a video. → Daily word goals and reminders: stay consistent without overwhelming study sessions. BUILT FOR EACH LANGUAGE Japanese → Furigana, romaji, or no reading aids. Your choice. → Pitch accent graphs and dictionary meanings on every card. → Anime, J-pop, podcasts, streams, and more, levelled from Pre-JLPT to N1. Mandarin Chinese → Pinyin with tone marks, or turn it off. → Simplified characters, with traditional forms shown alongside. → C-dramas, music, and more, levelled from Pre-HSK to HSK 6. WHAT YOU'LL LEARN ◆ Real vocabulary and phrases, the way native speakers actually use them. ◆ Listening and reading skills through authentic videos, songs, and clips. ◆ Words from the shows, music, and creators you already watch. ◆ Language you'll actually hear, not just textbook examples. WHO IT'S FOR → Anime, J-pop, C-drama, and music fans who want to learn from what they already love. → Learners who already spend hours watching videos and scrolling online. → Travelers, international students, and people living or working abroad. → Busy learners who want immersion to fit naturally into their day. → Anyone tired of repetitive textbook lessons and overwhelming flashcard decks. HOW IT WORKS 1. Choose Japanese or Mandarin Chinese and your level. 2. Watch a video, scroll Moments, or sing along with a song. 3. Tap unfamiliar words to see what they mean and save them. 4. Gravity turns your saved words into flashcards, each linked to its original moment. 5. Review a few minutes a day and watch your known words grow. LEARN THROUGH WHAT YOU LOVE Doomscroll in the language you're learning. Watch videos. Sing your favorite songs.

MIMORI - DOOMSCROLL YOUR WAY TO LEARN JAPANESE Turn "just one more video" into one more Japanese word. Mimori helps you learn through short, engaging clips from native speakers. Scroll your feed, discover new words, and hear how Japanese sounds in real life. Whether you're planning a trip to Japan, obsessed with anime, or starting from zero, Mimori turns your everyday scroll into time spent learning. THE FEED THAT HELPS YOU LEARN • Swipe through short clips of cooking, comedy, travel, street food and everyday life in Japan. • Every clip comes with its Japanese transcript, broken into words you can tap the second you're curious. • Watched it? It's gone. Your feed is always something new. • Too fast? Drop to 0.75x. Feeling brave? Push it to 1.5x. TAP ANY WORD. KNOW IT IN SECONDS • A complete Japanese dictionary with more than 200,000 entries lives inside the app, and it works offline. • Type it however you know it: kanji, kana, romaji or plain English. • Hear it said out loud. • Look a word up mid-video and pick up exactly where you left off. REMEMBER IT FOR GOOD You don't forget a word you met in a story. That's the whole idea. • Save any word with one tap, and it becomes a flashcard automatically. • Each card shows the sentence you found it in, not a lonely definition. • Forgot how it sounded? Jump back to the exact moment in the video. • Sort your words into your own decks: food, travel, anime, whatever you're into. • Reviews take seconds. See it again today, or remember it for tomorrow. A HABIT THAT ACTUALLY STICKS • Pick a daily listening goal and watch your minutes stack up while you watch. • Keep your streak alive and see your words and hours grow. • A gentle daily reminder, only if you want one, at the time you choose. • Home Screen widgets that slip a saved word into your day. LONG VIDEOS, FOR WHEN ONE CLIP ISN'T ENOUGH • Conversations, podcasts, vlogs and listening practice, all 8 minutes or longer. • The transcript moves with the speaker and lights up the line you're hearing, so you never lose your place. • Missed something? Tap any line to jump right back to it, or skip 10 seconds either way. • Every word is still tappable. Put on an hour-long vlog and walk away with a pocketful of new vocabulary. SEE HOW WORDS ARE USED IN REAL CONTEXT • Search by word, topic or creator and find your next favorite channel. • Look up a word and hear real people use it in real videos. MIMORI IS FOR YOU IF • You've finished the beginner apps and still can't follow a real conversation. • You have a trip to Japan coming and want to understand what's being said around you. • You're tired of reading subtitles and want to just get it. • You're starting from zero and want to hear real Japanese from day one. Your next scroll is happening either way. Make it the one where Japanese starts to click. Download Mimori and learn your first word.
