Start from zero
Never studied Japanese? Moji begins with hiragana and katakana, writing practice included. Already past that? A short placement test finds your level and skips what you know.
Japanese that
actually sticks.
Your first kana or your last N1 word, it works the same: open the app, study for five minutes, put it down. Moji handles the annoying parts so you can just learn.

What's inside
A look inside.
- 01
On your Lock Screen
A new word every hour, next to your streak and what's due. You keep learning without opening the app.
- 02
Cards that explain themselves
Every word comes with a real example sentence and a mnemonic built from the kanji's actual parts.
- 03
Quiz what you've learned
Vocabulary, listening, and fill-in-the-blank. Get one wrong and the answer comes back with its meaning and a sentence.
- 04
Write it stroke by stroke
Trace kanji and kana in the right order, with the next stroke shown when you're stuck.
How it works
A five-minute loop you'll actually keep.
- 01
Swipe new words
Flip and swipe through new cards. They arrive in a sensible order, a few at a time.
- 02
Practice your way
Lock them in with quizzes, listening, even writing kanji and kana stroke by stroke.
- 03
Absorb between sessions
Widgets rotate your words on the Home and Lock Screen, so you keep learning without opening the app.
- 04
Review on time
Moji resurfaces each word right before you'd forget it. Then the loop starts again.
What it does
Four ideas. That's the whole app.
No deck-hunting
7,000 words from beginner to N1, curated and ordered so the words you meet first are the ones you'll actually use. No .apkg files to find, no add-ons to install, no setup.
It picks what to study
You set the daily target. Moji decides which cards to surface, right before you'd forget them. No tuning intervals, no rebuilding decks after a missed week.
Mnemonics that hold up
Each kanji is explained by what its parts actually mean, not a cartoon mascot that falls apart the next time you see the same shape.
Questions
Things people ask.
The download button isn't working?
Some apps open links in their own built-in browser, and those can block downloads from reaching the App Store. If you're reading this inside TikTok or another app, tap the ••• menu and choose Open in browser, then try again. You can also search the App Store for Moji - Learn Japanese Daily.
I've never studied Japanese. Is this for me?
Yes. Moji starts at zero: hiragana and katakana with writing practice, then real words in an order chosen for beginners. You don't need a JLPT goal, the levels are simply there when you want them.
Why not just use Anki?
Anki is powerful, but most learners spend more time curating decks than reviewing them. Moji ships a curated word list, a predictable daily load, and mnemonics tied to real kanji components, so you can skip the setup and just study.
Full comparisonIs it free?
Mostly, yes. Every word, every level, the mnemonics, and the full SRS schedule are free, along with the vocabulary and kana quizzes, kana writing practice, and the widgets. Premium is an optional subscription that adds the extra practice modes: listening and fill-in-the-blank quizzes, AI conversation scenarios, pronunciation feedback, kanji writing, and advanced progress views.
Is there an Android version?
iPhone only for now. Moji is built natively for iOS so it stays quiet and fast: real haptics, system text, and dark mode without compromise.
