App Deep Dives
🟢 Duolingo — Habit Building for Beginners
Duolingo's gamified approach is excellent for building a daily study habit. The Japanese-to-English course is well-designed for absolute beginners. Its biggest weakness: it doesn't teach you to produce natural English conversation. Think of it as a warm-up, not a complete program.
Best used for: 10-minute daily streaks, reviewing basic grammar and vocabulary.
🟢 Anki — The Gold Standard for Vocabulary
Anki uses spaced repetition — a scientifically proven method that shows you flashcards at exactly the right intervals to maximize memory. It's less polished than commercial apps, but the results are hard to beat for vocabulary retention. Download free Japanese-English shared decks or build your own.
Best used for: Learning and reviewing vocabulary over the long term. Pair with any other study method.
🟡 ELSA Speak — AI Pronunciation Coach
ELSA uses AI to analyze your English pronunciation and give specific feedback — for example, telling you your "r" and "l" sounds need work. For Japanese speakers, who often struggle with sounds that don't exist in Japanese (v, r/l, th), this targeted feedback is valuable. The free tier is limited, but useful for trying it out.
Best used for: Dedicated pronunciation training sessions, 10–15 minutes per day.
🟢 HelloTalk — Talk to Real Native Speakers
HelloTalk connects you with native English speakers who want to learn Japanese. You help each other — you correct their Japanese, they correct your English. It's free, authentic, and one of the best ways to practice real conversation without paying for a tutor.
Best used for: Intermediate learners ready to start having real conversations.
🟢 BBC Learning English — Free & High Quality
The BBC Learning English website and app offers free podcasts, videos, and articles on grammar, vocabulary, and pronunciation. The content is professionally produced and covers everything from beginner grammar to advanced business English. It's completely free with no paywall.
Best used for: Listening practice, grammar lessons, and building real-world vocabulary.
推奨コンビネーション：Recommended App Stack
The most effective approach is to combine apps that each cover a different skill:
- Vocabulary: Anki (daily 5–10 min)
- Grammar & Listening: BBC Learning English (commute time)
- Speaking: HelloTalk or ELSA Speak (3x per week)
- Daily habit tracker: Duolingo (for keeping your streak)
まとめ
No single app will make you fluent. But the right combination, used consistently, will take you further than any classroom. Start with Anki and BBC Learning English — both are free and highly effective — then add a speaking app once you feel ready to practice conversation.
