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.
