Kanji Study

Most language apps make a trade you don’t notice at first. They reward you for showing up rather than for what you learn, and the streak counter slowly becomes the goal. Kanji Study doesn’t do this, and that is the main reason it deserves attention.

The app is built by independent developer Chase Colburn and listed on Google Play as “Japanese Kanji Study – 漢字学習”. For an education app, its reputation is unusually strong, because learners tend to blame the tool when they get frustrated. Kanji Study comes up again and again when Android users ask what to install after they finish the kana.

Its scope is deliberately narrow. This is not a full Japanese course. There are no grammar lessons, listening drills or chatbot tutors. Kanji Study aims at the hardest part of written Japanese for most learners: thousands of characters, each with several readings, a set of meanings and a stroke order that matters more than beginners expect. The app sorts these into levels based on JLPT tiers and Japanese school-grade lists. Those are the two orders serious learners already use, so the progression makes sense from the start.

The business model sets it apart just as much. The free tier has no ads, and it covers beginner kanji, radicals, hiragana and katakana with no study limits. A single one-time purchase unlocks the higher levels and custom sets. There is no subscription, no energy meter and no nagging. Most of the education category earns money through recurring billing and pressure tactics, so Kanji Study’s pricing is almost old-fashioned. That puts it squarely against subscription platforms such as WaniKani, and against the flashcard-deck route of Anki, which is more flexible but much harder to set up.

• Structured Kanji Progression: Characters are grouped into levels and sets taken from JLPT and Japanese school-grade lists, so you move from simple to complex in a set order.
• Detailed Kanji Entries: Each character includes on’yomi and kun’yomi readings, meanings, radicals, stroke-order animations and example vocabulary with sample sentences.
• Handwriting Challenges With Stroke Checking: You draw each character on screen and the app checks your strokes, which makes writing practice something you actually do.
• Spaced-Repetition Scheduling: The SRS brings back characters you struggle with more often and spaces out the ones you know well.
• Multiple Study Modes: Flashcards, multiple-choice quizzes and writing drills all use the same underlying review data.
• Kana and Radicals Included: Hiragana, katakana and radicals are built in, so complete beginners can start with no background.
• Flexible Search: You can look up kanji and words in several ways, so the app also works as a reference.
• Custom Study Sets: In the paid tier you can build your own sets, for example the characters from a textbook chapter or a manga you’re reading.
• Progress Statistics: Detailed stats show what you know, what’s slipping and where you’ve stalled.

The Core Loop: Recognition, Recall, Production

Kanji Study trains all three stages of learning a character, where many competitors stop at the first.

Recognition is the easy stage: you see 語 and know it means “language.” Multiple-choice quizzes cover it, and they get you through a lot of characters quickly. Recall is harder: you see a meaning or reading and have to produce the character yourself. Flashcards test this, and so does SRS review done honestly. Production, meaning writing the character correctly from memory, is where most apps give up. Kanji Study doesn’t.

The writing challenges do the most to justify the app. You draw the character on the touchscreen, and the app checks the strokes rather than just comparing the final shape. That difference matters. A kanji with a wrong stroke order can look fine and still be wrong, and the habit causes problems later. Characters get denser, and handwritten or cursive forms only make sense if you learned the strokes correctly. An app that only checks recognition lets you believe you know a character when you don’t. Stroke checking catches that.

Writing drills also help memory beyond the handwriting itself. Building a character stroke by stroke forces you to handle its parts: the radical on the left, the phonetic part on the right. Once you learn those parts, new characters become combinations of pieces you already know instead of shapes to memorize from scratch. The radical coverage supports this well. Radicals are available from the free tier on, and each kanji entry lists them, so the structure of the writing system stays in view.

The SRS Engine

Any serious kanji tool needs spaced repetition. Without it, you forget faster than you learn and eventually drop the app. Kanji Study’s SRS does the expected job: characters you miss come back sooner, and characters you know drift into longer intervals.

What matters more is how the scheduler fits with the rest of the app. Because flashcards, quizzes and writing drills all live in one place, your reviews aren’t locked into one format. You can clear a review pile with quick recognition cards on a commute and switch to writing at home when you can focus. Anki is more configurable, but getting this kind of mixed practice there takes add-ons, card templates and a lot of patience. Kanji Study includes it by default.

There is a tradeoff. WaniKani’s fixed curriculum is strict on purpose, which some learners need and others can’t stand. Kanji Study gives you more control over what you study and when. That suits self-directed learners, but an undisciplined student can pick only the easy material. The statistics screens help: they make weak spots hard to ignore. Still, the app won’t push you forward if you avoid your hard characters.

Entries as a Reference Tool

Each kanji entry works as a small dictionary page. Both reading types, meanings, radicals, an animated stroke order, and example vocabulary with sample sentences are shown together. The example sentences are especially useful. A character learned alone is trivia. A character learned inside a word inside a sentence is something you can use.

Search goes in several directions, so the app also works as a lookup tool while you read. For intermediate learners working through real texts, it can replace a separate dictionary app for kanji lookups. That turns a study tool into something you open every day, even on days you don’t review.

Onboarding and Progression

Including hiragana and katakana is a smart choice. Complete beginners don’t need a separate kana app first, and the free tier covers both scripts with no limit. It’s a low-friction start. A new user can learn the kana, then the beginner kanji and radicals, without paying anything or seeing an ad.

The paywall appears where it should: once you’re committed. When you reach the higher levels, you already know whether the app works for you. Paying once at that point feels like buying a tool, not renting access.

Where It Falls Short

The focus on kanji is intentional, but it has limits. The app won’t teach you grammar or listening, so it has to be paired with other resources. Also, completeness brings density. There are a lot of study modes, set options and statistics, and a brand-new learner may have to explore for a while before building a routine. The design suits learners who want control, not ones who want a single “study now” button and nothing else.

Kanji Study cares more about function than looks, and in this category that’s the right priority. Its main visual job is to present characters large and clear, with readings and meanings easy to find, and the design is built to do that. The stroke-order animations are the key visual element, and they’re designed to be clear and easy to follow. For a learner, that’s worth more than any number of mascots or confetti effects.

The interface is information-heavy rather than showy. Kanji entries stack a lot of data, and the design leans toward showing everything instead of hiding it behind tabs. Experienced learners will like it. Casual users coming from gamified apps may find it plain. It’s utilitarian, not ugly, and the absence of ads keeps the screen free of the clutter that ruins many free study apps.

A 2D study app of this kind is light on hardware, and nothing in the design suggests it should strain a modern Android phone. The most technically demanding part, real-time stroke recognition, is also the feature the app is built around, and it’s the one that has to be reliable for the whole approach to work.

Kanji Study is Android-only, and that fact defines who can use it.

On Android the app plays to the touchscreen’s strengths. Handwriting practice works naturally with a finger, and even better with a stylus on phones or tablets that support one. Drawing on a tablet with a pen is about as close as digital practice gets to writing on grid paper, while still giving you instant stroke feedback. Quick flashcard and quiz sessions fit phone use well: thirty seconds of reviews in a queue, a few minutes on a train.

The downside is significant. There is no current iOS version, and the App Store contains several unrelated apps with similar names. iPhone users searching for “Kanji Study” may install a clone and think they have the real thing. The missing iOS version is the most obvious complaint to raise, and a reasonable one. For a one-time-purchase product, not being able to take your progress to another platform is a real risk if you might switch phones.

Kanji Study doesn’t reinvent language learning, and it doesn’t claim to. What it does is rarer: it does one hard job almost completely and charges fairly for it. Stroke-checked writing, a working SRS, detailed entries and a sensible JLPT-based order would each make a respectable app. Together, with an ad-free free tier and a single unlock, they make a genuinely strong kanji tool on Android.

The Android-only limit is a real problem, and the pile of App Store clones makes it worse. The narrow scope means Kanji Study has to be combined with other resources to make a full curriculum, and the dense interface asks more of a newcomer than it should. But in its own area it has no real Android competitor. If you’re learning Japanese on an Android device, we recommend starting here.
