The Japanese learning app market has exploded. There are now dozens of apps claiming to make you fluent — but they are not all equal. Some are genuinely transformative; others are beautifully designed time-wasters. This comparison covers the major Japanese learning apps, what each one is really good at, and a clear recommendation for each type of learner.
A note on bias: LenGaki publishes this blog, and LenGaki is one of the apps below. We compared the apps on curriculum, review system, JLPT alignment and cost, stuck to facts you can check on each app's own site, and said where other apps do a job better. There are no sponsored placements or affiliate links in this post.
The Core Problem with Most Japanese Apps
Streaks, XP and reminders are great for building a daily habit (LenGaki uses them too), but they aren't a curriculum. A long streak doesn't mean you can read a menu. Effective apps pair the habit with regular review, grammar depth, and JLPT-aligned content.

Category Winners — Best App for Each Goal

| Learning kanji meanings and readings | 🥇 WaniKani | Radical-based mnemonics for every kanji and a strong review system (it doesn't teach stroke order) |

WaniKani — The Kanji King
WaniKani uses a radical → kanji → vocabulary learning sequence that is genuinely brilliant for kanji acquisition. If kanji is your bottleneck (it usually is), WaniKani's system of mnemonic stories is unmatched. However, it teaches only kanji and vocabulary, and not stroke order or handwriting — you need a separate app for grammar (Bunpro or LenGaki).
Anki — The Infinitely Customizable SRS
Anki's scheduler, based on SM-2 with the newer FSRS algorithm available since version 23.10, is among the most effective spaced repetition systems available. Its weakness: it requires significant setup time. You need to find or build good Japanese decks, format them correctly, and maintain them yourself. Not ideal for beginners; powerful for intermediate+ learners.
Duolingo — The Motivation Starter (Not a Complete System)
Duolingo is excellent for building the habit of daily study and for learning hiragana and katakana. Its strength is gamification — streaks, leaderboards, and animations keep beginners coming back. Its weaker points: grammar explanations are light, it doesn't follow the JLPT, and kanji coverage is limited. Many learners use it to build the habit, then move to a structured system.
