Description by Heimdall Space Inc. (from Google Play)
**ABOUT THIS APP**
◆ Learn Japanese from the podcasts, videos, and songs you actually want to hear — and the language you see in daily life.
◆ Gravity is a personalized Japanese learning app built around real native media. Play from a curated library of transcribed Japanese podcasts, streams, songs, and YouTube videos, follow along word-by-word with synced transcripts, and tap any word to turn it into a flashcard — the original moment it came from stays attached, so you always remember where you learned it.
◆ Prefer to learn from the world around you? Snap photos of menus, signs, manga, subtitles, or everyday Japanese text and pull vocabulary straight from it too.
◆ Whether you're preparing for a trip, studying abroad, living in Japan, or simply immersing yourself through anime, music, and media, Gravity helps you build confidence through real context instead of generic textbook lessons.

**WHY CHOOSE GRAVITY?**
→ Learn from real native media: a curated library of Japanese podcasts, streams, songs, and videos, levelled N5–N1 so you're always understanding just enough.
→ Word-synced transcripts: follow along word-by-word as audio plays — tap anything you don't know to save it instantly.
→ One-tap flashcards: turn any word from media, photos, or screenshots into study material in a single tap — zero setup.
→ Context that sticks: every saved word keeps the original clip, sentence, or image it came from, so you review it in the moment it appeared.
→ Personalized learning: your lessons are built around the Japanese you actually listen to, watch, and encounter every day.
→ Smart review system: spaced repetition surfaces the most useful and frequently encountered words first.
→ Capture the real world: pull vocabulary from menus, signs, manga, subtitles, conversations, and screenshots whenever you're offline or out and about.
→ Daily learning plans: manageable study sessions tailored to your progress and goals.

**WHAT YOU'LL LEARN**
◆ Real spoken Japanese from podcasts, streams, songs, and videos — the way natives actually talk.
◆ Listening and reading practice through word-synced transcripts, signs, menus, subtitles, and media.
◆ Real-world vocabulary and phrases used in everyday situations.
◆ Common expressions for travel, restaurants, shopping, school, and conversations.
◆ Personalized vocabulary based on your interests, hobbies, and environment.
◆ Japanese you'll actually encounter — not just textbook examples.

**WHO IT'S FOR**
→ Anime, manga, J-pop, and podcast fans who want to learn from what they already love.
→ Travelers preparing for Japan trips.
→ International students and exchange students.
→ Immigrants and working-holiday travelers.
→ Busy learners who want low-friction daily immersion.
→ Anyone who wants to stay consistent without overwhelming flashcard decks.

**HOW IT WORKS**
1. Play something from the library — a podcast, song, stream, or video — and follow along with the word-synced transcript.
2. Tap any word you want to learn (or snap a photo / upload a screenshot of Japanese text).
3. Gravity builds personalized flashcards and learning plans automatically, with the original context attached.
4. Review daily and track your progress over time.

The more Japanese you listen to, watch, and encounter, the smarter your learning experience becomes.

**Start learning Japanese naturally**

Gravity helps you learn through the media and the world around you — making Japanese feel more practical, personal, and connected to your daily life.

**GRAVITY IS IN EARLY ACCESS.**

Comments on Gravity - Language Immersion for Android

★★★★★ emma lau · Sep 6, 2026
Good for immersive based learning, and honestly I love the doomscroll
★★★★☆ JM · Oct 10, 2026
I would only use this for learning new words. Learn the grammar and basics elsewhere because it is not always 100% accurate. Especially when a sentence continues onto another section separately. It seems to guess the first part and then tag the second part on incorrectly. But it is still amazing for learning new words and how different media forms use them.
★★★★★ Eve Bennett · Oct 22, 2026
This is actually so awesome for an intermediate learner like me where textbook lessons get really boring and dry, but I can't quite just watch shows on my own due to the speed. Really excited to get back into practicing Mandarin Chinese again thanks to this launch!
★★★★☆ Runa Prayascitta · Oct 4, 2026
A great app for learning practical, everyday Japanese vocabulary. My only issue is that words you struggle with don't come back for review. An Anki-style spaced repetition system that focuses on words you haven't mastered would make this a 5-star app!
★★☆☆☆ nick · Sep 26, 2026
Good app but they removed the one tool I was using as I learned japanese. They completely removed the ability to practice your katakana and hiragana. I used it almost every day and now its gone. Why?? There's no point it's not like you need to make updates to that section. Bring it back or I need a refund
★★☆☆☆ Paul bowen · Oct 12, 2026
7 pounds a month or 50 pounds a year is a lot to pay for subtitles on someone else's videos. They are free on YouTube.
★★☆☆☆ M V · Oct 9, 2026
Concept is cool, but the translations when watching videos are inaccurate and don't make sense most of the time. This is similar to if you Google Lens japanese text and get nonsense
★☆☆☆☆ Ryan Wade · Oct 2, 2026
Too many mistakes in subtitles to consider as a serious tool, and for CAD$60 a year? Add a lifetime and reduce price by alot and I would think about it. If it was $30 for lifetime I would, It's just another AI language learning tool
