Kanji Study versus Skritter is a common Apple App Store comparison, and the answer is not which one wins, it is which job you are hiring an app to do. They are built for different things, and neither is a pure writing-first tool. Here is the honest split, plus the gap both leave open.
The short answer
On iPhone and iPad, Kanji Study is a cheap recognition and reference app: free to download with a small set of characters, and a roughly 1.99 one-time unlock for the full 2,000-plus, with optional paid add-ons. Skritter is a subscription built around automated stroke grading and large prebuilt decks. If your real goal is writing kanji from memory daily for free, a dedicated writing-first app fits better than either.
Kanji Study, in brief
Kanji Study is strongest as a reference and quizzing tool. It is excellent for looking a character up, browsing by JLPT level or grade, and testing recognition with multiple-choice and writing challenges. The economics are friendly: most of the value is unlocked once for a small one-time price, with no subscription. Its writing challenge exists, but the app’s center of gravity is recognizing and reading characters rather than producing them from a blank screen every time.
Skritter, in brief
Skritter is the opposite trade. It is a paid subscription, but its handwriting engine grades each stroke for order and direction as you draw, and it ships with large decks and a spaced-repetition schedule so you can drill thousands of characters without building anything. If automated grading and volume are what you want, and a subscription is acceptable, Skritter does that job better than a cheap reference app ever will.
Head to head
| Kanji Study | Skritter | |
|---|---|---|
| Price | Free core, about 1.99 one-time unlock | Subscription, 7-day trial |
| Main job | Recognition, reference, quizzing | Automated stroke grading and volume |
| Writing from memory | Writing challenge mode | Yes, graded per stroke |
| Apple devices | iPhone and iPad | iPhone and iPad |
| Best for | Cheap lookup and study | Paid grading at scale |
The gap neither fills: writing-first practice
Notice what both apps treat as secondary: sitting down and writing characters from memory as the main event. Kanji Study leads with recognition, Skritter leads with grading and decks. Producing the character cold, prompted only by meaning and reading, is the skill that recognition study skips, and it is a category of its own. We explain why in recognition versus recall.
That gap is the niche Kanji Write Practice is built for: a calm, writing-first daily loop that prompts you with meaning and reading, asks you to draw the character, and keeps a stroke-order guide a tap away, free in early access. If you are choosing between cheaper Apple options for writing, see our Kanji Study iOS alternative and free Skritter alternative guides.
In practice the gap looks like this: you can ace a Kanji Study quiz and pass a Skritter review, then sit with a blank page and still blank on how a character like 議 actually starts. Recognition and grading both assume the character is already in front of you in some form. Writing from memory removes that crutch, which is why it is the skill that transfers to a real exam or a handwritten note.
Who each app is for
Concrete profiles make the choice obvious:
- Choose Kanji Study if you want an affordable reference you own outright: a learner who looks characters up constantly, browses by grade or JLPT level, and quizzes recognition without paying monthly.
- Choose Skritter if you are a heavy daily driller who wants every stroke graded automatically and a large library ready to go, and a subscription does not bother you.
- Add a writing-first app if your weak spot is producing characters cold, because that is the gap both leave open.
A note on origins
Kanji Study built its reputation as a deep, affordable study and reference tool with one-time pricing. Skritter built its reputation on handwriting recognition and grading across both Chinese and Japanese. Knowing each app’s center of gravity explains why neither leads with from-scratch writing practice: it was never the main promise. That is not a flaw, it is focus, and it is why a dedicated writing app exists alongside them rather than trying to replace either.
Which to pick
Pick Kanji Study if you want a cheap, no-subscription reference and recognition trainer. Pick Skritter if you want automated stroke grading and large decks and do not mind paying. Add a writing-first app on top of either if your weak point is producing characters by hand from memory, because that is the one thing neither is designed around.
