01 · The loop

Kanji first,
the honest way

Reading kanji is the skill the JLPT actually tests. Furigana upfront would answer half the card, so here, your memory goes first.

θ‡ͺ軒車

The kanji alone. Kana-only words show their reading upfront, because the reading is the word.

02
Your guess

“Ji…tensha?”

Try the reading before you tap. Two seconds of honest recall.

The details
a learner notices

01

True Japanese glyphs

Kanji render in a Japanese Mincho face, so shared characters take their Japanese forms, never the Chinese ones.

02

Reading on the reveal

Furigana arrives after your guess, so the widget quizzes the exact skill the JLPT grades.

03

Kana words, kana first

Words written in kana show their reading upfront. There is nothing to hide when the reading is the word itself.

04

Nothing collected

No accounts, no tracking, notifications opt-in. Everything lives on your device.

04 · Lock&Learn+

Every level opens with a free preview. Plus opens them all.

Another word unlocks each day at no cost. Lock&Learn+ opens every JLPT level at once, so the widget can walk you toward N1.

Asked and
answered

How do I put Japanese flashcards on my iPhone Lock Screen?

Install Lock&Learn Japanese, then touch and hold your Lock Screen, tap Customize, tap the widget area, and choose Lock&Learn Japanese. A JLPT word will wait there every time your screen wakes. There is a Home Screen widget too.

Which JLPT levels does Lock&Learn Japanese cover?

Every level, from N5 all the way to N1. Vocabulary is organized by level, so you can start where you are and let the widget walk you toward the next exam. N5 is free.

Is Lock&Learn Japanese free?

Yes. The app is free on iOS: N5 is free, every other level opens with a free preview, and another word unlocks daily. Lock&Learn+ is an optional upgrade that opens every JLPT level at once, offered as a yearly plan with a free trial or a one-time lifetime purchase.

Why does the widget show kanji without furigana?

Reading kanji is the skill the JLPT actually tests, and furigana upfront would answer half the card. So the kanji waits alone, you try the reading, and the furigana and meaning arrive on the tap. Words written in kana show their reading upfront, because the reading is the word itself.

How is this different from a regular flashcard app?

There is no session to sit down for. The word waits on the screen you already look at dozens of times a day, you recall it before you tap, and the meaning arrives with a real example sentence. Learning happens in the seconds you were going to spend anyway.

Do I need an account?

No. There are no accounts and no tracking. Streaks, saves and progress live on your phone and nowhere else, and notifications are opt-in. More in the Privacy Policy or on the Support page.
