(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.

Learn a language by scrolling. Scrollingua turns short videos into real language practice — watch, tap any word for its meaning, and pick up vocabulary you'll actually use. Learn Japanese, Korean, Chinese, Spanish, French, or German in the format you already scroll every day. You already spend time scrolling short videos. Scrollingua puts that habit to work, so time you'd spend on autopilot becomes listening practice, new words, and real comprehension. No sitting still. No starting over from lesson one. Learn 6 languages: Japanese, Korean, Mandarin Chinese, Spanish, French, and German. Japanese includes full furigana and romaji, Chinese includes pinyin, and every language comes with a built-in dictionary and color-coded grammar hints tuned to how that language actually works. How to use Scrollingua 1) Pick your language and take a quick placement check. 2) Scroll a feed of authentic short videos with interactive subtitles. 3) Tap any word to see its meaning, reading, and grammar role — without leaving the video. 4) Save the words you want to keep; they come back as spaced review so they stick. 5) Follow a guided lesson path when you want structure, from the basics up to real sentences. 6) Practice speaking out loud and get pronunciation feedback on how you did. Built for people who love the idea of learning a language but bounce off traditional study. The loop is familiar on purpose — swipe, tap, listen, repeat. A few minutes between other things adds up faster than you'd expect, and streaks, daily goals, and friends keep you coming back. Ditch flashcard drills and lessons that feel like homework. Scrollingua is language learning that fits the way you already use your phone, so the practice happens without you having to schedule it.
