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.

Verdict
The clearest difference is rating: Kitsugo at 5.0 against Gravity's 4.2. Gravity's advantage is ratings volume (45 vs 2) and update cadence (weekly vs every 2 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Gravity sells 6 in-app purchases, starting at $4.99 per month and Kitsugo sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
Kitsugo holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Gravity has 45 ratings behind it against 2, so its average is the more settled of the two.
Gravity ships an update weekly, Kitsugo every 2 weeks. The most recent releases landed on November 7, 2026 and October 31, 2026 respectively.
