5 Best Anki Alternatives for Japanese: Inku Is Our Pick

We recommend Inku as the first Anki alternative for most Japanese learners who want prepared daily review on iPhone. It supplies the Japanese catalog, bundled audio, and FSRS queue, so switching removes deck selection and template maintenance. Choose a different alternative when your reason for leaving Anki is broader study, media-specific vocabulary, a fixed kanji sequence, or grammar practice. Ownership disclosure.

This is a switching guide, not a list of apps that happen to use spaced repetition. Start with the problem Anki is not solving, then move only that job.

The alternatives by reason to switch

If you want to leave Anki because…	Start with	What stays familiar	What changes	Migration limit
You want prepared Japanese review on iPhone	Inku	Daily graded reviews and FSRS scheduling	Kana, vocabulary, kanji, phrases, and audio arrive as one maintained library	No Anki deck or review-history import
You want several Japanese skills in one system	Renshuu	Scheduled review and the option to study a small set	Curated and user-made lessons, dictionaries, varied quizzes, grammar, listening, and games share one account	Treat it as a fresh study path unless your exact data transfer is confirmed
You want vocabulary for a show, novel, or text	JPDB	Vocabulary and kanji reviews with flexible pacing	Prebuilt media decks and paste-in text decide what to learn	Anki database import is explicitly partial; inspect the result before relying on it
You want the app to choose a kanji sequence	WaniKani	Timed reviews and a clear daily queue	A fixed radical, kanji, and vocabulary level path replaces deck ownership	Your Anki order and history do not become WaniKani levels
You want grammar retrieval instead of flashcards	Bunpro	Scheduled prompts and honest recall grading	Grammar points, sentence prompts, readings, and vocabulary decks become the focus	Keep vocabulary and specialist cards elsewhere; this switch only replaces grammar review

Best first alternative for prepared Japanese: Inku

Inku is our recommendation for most Japanese learners who want less setup. Its native iPhone app includes 208 kana, 2,701 vocabulary cards, 429 kanji, 436 phrases, and 6,000 bundled audio clips. Reviews use FSRS, but you do not have to choose a shared deck, maintain templates, or configure the scheduler before studying.

The tradeoff is clear. Inku does not import Anki decks or history. Its personal-card feature can hold words you meet, but it does not offer Anki’s field, template, add-on, and collection system. The full prepared catalog is native to iPhone. A separate account-based web app has a smaller selection, and web progress does not sync with iPhone.

Choose Inku when the daily friction is deciding what to review. Keep Anki when you already have a useful collection or sentence-mining workflow. Try Inku with one small bundle before moving another study job.

Best for a broader Japanese system: Renshuu

Renshuu is the alternative when Anki feels too narrow rather than merely too configurable. Its official site combines vocabulary, kanji, grammar, sentences, listening, dictionaries, varied question types, games, curated lesson packs, and thousands of staff and user-made lessons. It can adjust how Japanese is displayed based on what you know, and you can begin free.

That breadth changes the commitment. You are moving from a card engine into a larger Japanese-learning account with several study surfaces. Pick one prepared lesson path first. Do not recreate every Anki deck while also activating every Renshuu schedule.

Choose Renshuu when you want review connected to dictionaries, grammar, and varied practice. Choose Inku when a quieter native iPhone review queue is enough.

Best for media vocabulary: JPDB

JPDB fits a specific reason to leave Anki: you want vocabulary from a particular anime, novel, visual novel, or pasted text without building the deck yourself. Its official site provides thousands of prebuilt media decks, extracts words from text, teaches kanji needed for vocabulary, and tracks learned words across decks.

JPDB says it can partially import an existing Anki database. The word “partially” should shape your plan. Keep the original Anki export, inspect which notes and progress arrived, and do not delete the source collection after one successful login.

JPDB currently runs on the web and does not have a native mobile app. Choose it when media coverage is the job. Keep Anki when your personally written cards contain context the importer cannot preserve.

Best for a fixed kanji path: WaniKani

WaniKani removes the kanji curriculum decision. It teaches radicals, then kanji, then related vocabulary through mnemonics, levels, and scheduled reviews. The official overview describes more than 2,000 kanji and 6,000 vocabulary words. The first three levels are available free.

This is a different job from replacing all of Anki. WaniKani does not become your sentence-mining deck, grammar notebook, or specialist vocabulary archive. Its fixed sequence is useful when you want the app to decide what kanji comes next, and restrictive when you need the characters from your current book now.

Choose WaniKani for a dedicated kanji path. Keep Anki for the material WaniKani does not try to own.

Best for grammar retrieval: Bunpro

Bunpro is the alternative when vocabulary cards are not the problem. Its official product focuses on grammar SRS, sentence prompts, vocabulary decks, readings, and a large bank of examples. It has web, iPhone, and Android access and offers a trial.

Switching this job means accepting that grammar needs context. Bunpro can schedule recognition and production prompts, but it does not turn a broad Anki collection into a grammar course. Use it alongside reading, listening, and real output.

Choose Bunpro when you recognize grammar in a lesson but cannot retrieve it in a sentence. Keep Anki for personal vocabulary or audio contrasts that fall outside Bunpro’s prepared paths.

Protect your Anki collection first

Before testing any alternative, create a backup you control. Anki’s official manual says a collection package can include every deck and its scheduling information. Include media if audio and images matter. Keep that file somewhere separate from the device you normally review on.

Then write down what you are trying to replace. “Anki has too many options” points toward Inku. “I want my show’s vocabulary” points toward JPDB. “I need a kanji order” points toward WaniKani. “I need grammar prompts” points toward Bunpro. A vague desire for a new interface is not enough reason to abandon useful history.

Try before you commit

Use this checklist:

1. Export the relevant Anki deck or full collection with scheduling and media.
2. Name one job the alternative will own.
3. Start with its smallest free level, free plan, or trial.
4. Pause new Anki cards for that job instead of deleting the deck.
5. Run the alternative long enough for early cards to return.
6. Compare setup time, queue clarity, content fit, and platform access.
7. Keep one owner for each item so the same word does not build two queues.

If Anki already holds carefully edited cards from your reading, audio, class, or profession, staying is a valid decision. Anki works without add-ons, supports prebuilt decks, and gives you more control than these alternatives. Switching is useful when another product removes a specific bottleneck, not when it merely gives you a new streak.
