A Japanese app built entirely around immersion reading. The best way to learn to read Japanese isn’t by hours of flashcards or grammar textbooks — it’s by actually reading Japanese. Because reading doesn’t just teach you how to read — it teaches you how to describe, reason, and think in Japanese too. Reading doesn’t just teach you kanji — it builds fluency. And true fluency comes from immersion: real context, real sentences, real Japanese. That’s why we built Yomoyo, so you can have your reading content, dictionary, and study tools for immersion all in one place. 読もうよ! -- KEY FEATURES -- • Real Japanese Content Read authentic Japanese from real sources — including folktales, Japanese news articles, Wikipedia, and original stories written by Japanese authors. • Scan Physical Books Snap a photo of any Japanese book. Yomoyo pulls out the text so you can read it with furigana, dictionary lookups, and more. • AI-Powered Reading Generator Type in a topic — anime, travel, cooking, whatever you want — and instantly get a Japanese story for your reading level and interests. • Pop-up Dictionary + Kanji Breakdown Tap any word to instantly see its definition, reading, pitch accent, and a breakdown of each kanji character. No need to switch apps or guess — it’s all right there. • Vocabulary Lists + Flashcards Every word you tap can be saved to a vocabulary list and studied later with flashcards. • Export to Anki Prefer Anki or other SRS software? Export any vocab list as .tsv files to keep your flashcard system in sync. • Favorites & Recents Save your favorite stories and access them anytime — even offline. Your recently read stories are also stored automatically so you can pick up where you left off. • Furigana Toggle Show or hide furigana to control how much help you want. -- CONTACT -- Have questions or need support?

Verdict
The clearest difference is rating: Yomoyo at 5.0 against Immersion Reader's 4.0. Yomoyo also leads on review sentiment (100% vs 62%). Immersion Reader's advantage is ratings volume (26 vs 3) and iOS requirement (13.0 vs 18.2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Immersion Reader sells 1 one-off in-app purchase and Yomoyo sells 6 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
Yomoyo holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Immersion Reader has 26 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 62% of Immersion Reader's written reviews are positive against 100% of Yomoyo's.
