Moji vs Kanji Study: Which Kanji App Is Right for You?

Moji is our app. Kanji Study, listed on Google Play as Japanese Kanji Study by Chase Colburn, is one of the most capable kanji apps on Android, and we say so happily. Note that several unrelated apps use similar names, including an iPhone app called Kanji Study - Learn Japanese! from a different developer. This page is about the Android app by Chase Colburn.

How each app teaches kanji

Kanji Study is a toolkit. It offers flashcards in manageable sets with stroke animations, readings, meanings and examples, multiple-choice quizzes that adapt timing and distractors to your results, and writing challenges. You can study in sequences such as JLPT levels and Japanese school grades, or build custom sets. Its search covers over 6,000 kanji and 180,000 words and works offline, and each kanji's info screen breaks down its radicals and shows example words, sentences and names. Optional add-ons include Guided Study, which adds unlimited use of an SRS module, and Graded Reading Sets with more than 30,000 mini reading exercises.

Moji is a guided course. It covers 2,140 kanji from JLPT N5 to N1 and introduces 1 to 20 new characters a day, at the pace you set. Short Continue Learning sessions rotate through memory stories, writing, radicals and reading in context. Radical Builder has you complete a kanji from three components, and the Confusables Drill separates look-alikes. Adaptive spaced repetition, rated Again, Hard, Good or Easy, is part of the core app.

Building a daily habit

Kanji Study supports custom study reminders and lets you add home screen shortcuts that open a particular study set. That suits learners who already know what they want to practice.

Moji puts the practice itself on the screen. Lock Screen widgets on iPhone and Home Screen widgets show a kanji with its reading and meaning, the medium Quick Quiz widget lets you rate a review without opening the app, and Kira's Review Pile widget shows what is due and your streak. Inside the app, the smart learning home points you to your next best action.

Writing practice

This is close. Kanji Study's writing challenges use stroke detection to teach correct stroke order, snap correct strokes into place, show hints when you struggle, and offer a self-assessment mode. Moji's guided writing checks stroke order, start point, direction, shape and length, then moves you to outline practice and full recall writing from memory, with hints, undo and retry. Both are strong. Try both if handwriting is your main goal. Our kanji stroke order tool is a free reference too.

Price and platforms

Kanji Study's free version has no ads and includes unlimited study of beginner kanji, radicals, hiragana and katakana, plus the full dictionary and info screens. A one-time upgrade unlocks the remaining kanji levels and custom sets, and add-ons are sold separately. As of October 2026, Google Play lists its in-app items at $1.99 to $29.99 each. It is an Android app, and we did not find a current listing for it on the US App Store.

Moji is a free download on iPhone, iPad and Android, and learning requires Moji Pro: $7.99 per month or $69.99 per year on the US App Store, with a lifetime purchase also listed and a free trial for eligible new users. For Android users who dislike subscriptions, Kanji Study's model is a real advantage.

Using Moji and Kanji Study together

On Android you could use Kanji Study as your offline dictionary and reference, and Moji as your daily course and review queue. Keep reviews in one app so you do not schedule the same kanji twice. If you want just one: on iPhone, the choice is made for you; on Android, pick Kanji Study for depth and customization, or Moji for a guided path with widgets that do the deciding for you.
