Learn Japanese JLPT
Read full descriptionHide full description
Start your Japanese learning journey today! Learn Japanese combines two ways to master the language: a fun matching game for building vocabulary, and a brand-new structured JLPT Prep course that teaches real grammar, kanji, and vocabulary from beginner (N5) toward passing the JLPT. MATCH GAME • 20 themed scenarios (shopping, dining, travel, and more) • 4 difficulty levels, from Easy to Expert • 480+ Japanese words with kanji, hiragana, and romaji • Native Japanese audio pronunciation • Track stars, streaks, and progress JLPT PREP — NEW! • Structured lessons for JLPT N5, with N4 and N3 on the way • Real grammar points with example sentences, not just word lists • Kanji breakdowns: readings, stroke counts, and example words • Auto-generated quizzes to test what you've learned • Progress tracking per lesson KEY FEATURES: • Two complete learning modes in one app • Progressive difficulty for every skill level • Audio pronunciation throughout • Multi-language interface (English, Spanish, French, Chinese, Korean, Portuguese) • Offline play, no internet required • Light and dark mode • Daily streaks and achievement tracking FREE & PREMIUM: Learn Japanese is free to download, with Easy/Medium difficulty and full JLPT N5 content available to everyone. A single one-time Premium purchase unlocks Hard & Expert difficulty, JLPT N4 & N3 lessons (as they launch), and removes all ads. WHY CHOOSE LEARN JAPANESE? Most apps teach either vocabulary through games or grammar through textbooks — rarely both. Learn Japanese does both: build vocabulary the fun way, then study the grammar and kanji you actually need for the JLPT, all in one app. PERFECT FOR: • Complete beginners starting their Japanese journey • Students studying for the JLPT (N5 available now, N4/N3 coming soon) • Travelers visiting Japan • Anime and manga enthusiasts • Anyone serious about real Japanese fluency, not just flashcards

Verdict
The clearest difference is in-app purchases: Slyd.in at none against Learn Japanese JLPT's 1. Slyd.in also leads on ads (none vs shown). Learn Japanese JLPT's advantage is update cadence (every 3 days vs fortnightly) and device support (3 vs 1). On price and iOS requirement there is nothing between them.
