Kanji Study App Review 2026: Features, Pricing, and Who It’s Best For

What Is Kanji Study?

Kanji Study is a dedicated kanji learning application developed by Chase Colburn. Originally built for Android, it has become one of the most popular single-purpose tools for Japanese learners, with over 1 million downloads on Google Play and a 4.7-star rating from more than 61,000 reviews. The app's core value proposition is straightforward: it combines a comprehensive kanji dictionary, flashcard drills, writing practice with stroke detection, and structured study sequences into one package — all without requiring a recurring subscription.

Unlike many language learning apps that lock core features behind monthly fees, Kanji Study operates on a one-time purchase model. You pay once for the content you want, and you own it. This makes it an attractive option for learners who are tired of subscription fatigue and want a tool they can return to years later without worrying about an expired payment.

Platform Availability: Android vs. iOS

There is an important distinction to make upfront: the Android and iOS versions of Kanji Study are not identical products. The Android app, developed by Chase Colburn, is the original and more mature version. It has been refined over years and includes the full suite of features, add-ons, and community trust that come with a long track record.

The iOS version, published by Luli Languages LLC, is a separate port. It carries the same name and many of the same features — including writing lessons with stroke detection, spaced repetition, and full JLPT coverage — but it is a newer product. As of June 2026, it holds a 4.7-star rating from 6,800 ratings on the App Store, which is a strong signal, but it has not yet accumulated the same depth of user feedback as the Android original.

• Android version: Developed by Chase Colburn. 1M+ downloads, 4.7 stars (61K+ reviews). Full add-on support (Guided Study, Graded Reading Sets, Outlier Dictionary).
• iOS version: Published by Luli Languages LLC. 4.7 stars (6.8K ratings). Requires iOS 17.5 or later. Feature set is similar but pricing and add-on availability may differ.

Core Features: What You Get in the Base App

Even without purchasing any add-ons, the base Kanji Study app is a powerful kanji reference and practice tool. The free tier alone gives you unlimited access to beginner kanji, radicals, hiragana, and katakana — with no ads. This is rare for a free app and makes it a low-risk download for absolute beginners.

Once you unlock the full levels, the app opens up a massive database: over 6,000 kanji for search and reference, and a dictionary of more than 180,000 words. The study content is organized into sequences that align with the JLPT (N5 through N1, covering over 5,000 vocabulary words), Japanese school grade levels, and frequency-based lists. You can also create custom study sets.

• Flashcard study: Self-assessment based drills where you rate your recall of readings, meanings, and example words.
• Multiple-choice quizzes: Customizable by readings, meanings, or example words — useful for quick review sessions.
• Writing challenges: Stroke detection that checks stroke order and direction. Includes both free-draw and challenge modes.
• Kanji and word search: Look up any of 6,000+ kanji by reading, meaning, stroke count, JLPT level, or radical.
• Detailed info screens: Each kanji shows on'yomi and kun'yomi readings, English meanings, stroke order diagrams, radical breakdown, and example compounds with furigana.
• Native audio: Over 8,000 audio files for kanji readings and vocabulary.
• Google Drive backup: Sync your study progress and custom sets across devices.

The SRS Add-On: Guided Study

This is one of the most important details to understand about Kanji Study: spaced repetition is not built into the base app. It is available as a separate paid add-on called Guided Study. The app originally launched without any SRS functionality, and the developer added it later as an expansion.

Guided Study costs approximately $30 for levels N4 through N1. It adds a daily scheduling system that uses spaced repetition to determine which kanji and vocabulary you review each day. The algorithm schedules reviews at increasing intervals based on your performance, and it expands over time to test kanji-based vocabulary and writing. You can customize the daily workload, toggle which aspects are tested (reading, meaning, writing), and choose which kanji levels to include.

The system is gamified with experience points and leveling, which can make daily review sessions feel more engaging. According to one detailed review, the Guided Study is ideal for quick 5- to 10-minute daily sessions and "caters what kanji you'll study every day based on what you've already studied."

Additional Add-Ons: Graded Reading Sets and Outlier Dictionary

Beyond the base app and the SRS add-on, Kanji Study offers two more optional expansions that significantly extend its capabilities.

• Graded Reading Sets: Over 30,000 mini reading exercises designed to build reading comprehension. Priced at $30 for levels 2-10 and $40 for levels 11-23. These are essentially short passages that test your ability to read kanji in context.
• Outlier Kanji Dictionary: A $40 add-on that provides detailed etymological breakdowns of kanji, including ancient forms and component analysis. It is developed by Outlier Linguistics and is the same dictionary available as a separate product. A reviewer described it as "fascinating" but noted it is expensive.

These add-ons are entirely optional. Many learners will find the base app plus the Guided Study SRS sufficient. But if you want a complete kanji learning ecosystem — reference, SRS, reading practice, and etymology — the total cost adds up.

Kanji Study Pricing Breakdown (2026)

Kanji Study's pricing model is one of its strongest selling points. Unlike subscription-based competitors, every purchase is a one-time payment. Here is the full breakdown as of June 2026.

Who Is Kanji Study Best For?

Kanji Study is not for everyone, but for a specific type of learner, it is arguably the best single app available.

• Beginner-to-intermediate Japanese learners who want a single app for kanji reference, writing practice, and vocabulary study — without juggling multiple tools.
• Android users who want the most mature, feature-complete version of the app.
• Learners who prefer one-time purchases over subscriptions and want to own their study content permanently.
• JLPT-focused students who want structured sequences aligned with N5 through N1 levels.
• Learners who value writing practice with stroke detection and want to build handwriting skills alongside reading.

If you are an iOS user, the app is still a strong option, but you should be aware that the iOS version is newer and may not have all the add-ons available yet. For Android users, there is no better all-in-one kanji tool at this price point.

Limitations to Consider

No tool is perfect, and Kanji Study has several limitations that are worth considering before you commit.

• Self-led structure can overwhelm beginners: The app gives you a lot of flexibility, but it does not hold your hand. If you are new to kanji and prefer a guided, step-by-step curriculum, you may find the open-ended structure daunting. One reviewer described it as "supremely thorough" but noted it can be overwhelming.
• Add-on costs add up quickly: The base app is affordable, but if you want the full experience — SRS, reading sets, and the Outlier Dictionary — the total cost can exceed $100. This is still a one-time cost, but it is not as cheap as it first appears.
• Android-first history: The Android version is the original and has years of refinement behind it. The iOS version is a separate product and may not have feature parity or the same level of polish.
• SRS is not built-in: As noted above, spaced repetition requires the Guided Study add-on. If you are comparing Kanji Study to apps like Anki or WaniKani where SRS is core, factor in the extra cost.
• No built-in grammar or speaking practice: Kanji Study is laser-focused on kanji and vocabulary. It does not teach grammar, listening, or speaking. You will need other resources for those skills.

Kanji Study vs. The Alternatives

Kanji Study does not exist in a vacuum. Here is how it stacks up against the most common alternatives for Japanese learners.

Final Verdict

Kanji Study is a remarkable tool for Japanese learners who want a comprehensive, one-time-purchase kanji app. Its strengths are clear: a massive kanji and word database, excellent writing practice with stroke detection, structured JLPT-aligned sequences, and a pricing model that respects your budget over the long term. The free tier alone is generous enough to give you a real sense of the app before you spend anything.

The main trade-offs are the add-on costs (especially the SRS add-on, which many learners will consider essential) and the self-led structure, which may not suit beginners who prefer a more guided path. Android users get the best experience; iOS users should verify feature parity before purchasing.
