Lockana: JLPT N5 N4 Vocabulary

You don't need another study app. You need vocabulary that shows up where you already look. Lockana is a Japanese vocabulary widget for the iPhone Lock Screen and Home Screen. It shows one JLPT N5 or N4 word - kanji, reading, and English meaning - and rotates to a new word every 15 minutes. There is no app to open and nothing to remember to do. Your Lock Screen does the showing up. Every placed widget shows the same word at the same moment. Lock Screen and Home Screen never disagree, and checking your phone twice in the same 15 minutes shows the same word - the rotation runs on the clock, not on your attention. THE VOCABULARY, COUNTED • 718 N5 words • 668 N4 words • 1,386 words in total, organized by JLPT level Study N5, N4, or both - pick your level in settings. WHAT IS FREE, AND WHAT THE UNLOCK OPENS Free: 50 curated N5 words rotate on the widget, and every feature of the app works - settings, recall mode, the searchable word list, widget tap-through. The only thing the free tier limits is vocabulary breadth. A single one-time purchase of US$1.99 unlocks all 1,386 words - that is the only difference between free and unlocked. No subscription, no account, nothing recurring. If you reinstall or change phones, tap Restore purchase and your unlock comes back. NOTHING NAGS YOU No streaks. No hearts or lives. No notifications. No daily time ration. If you ignore your phone for a week, nothing punishes you. The words are simply there when you come back. BUILT FOR RECALL, NOT JUST RECOGNITION Flip one toggle to hide the English meaning on the widget. Read the kanji, recall the meaning yourself, then tap the widget to check — it opens straight to that word's entry in the app. THE WORD LIST All 1,386 words are browsable and searchable in the app - by kana, by romaji, or by English. Locked entries are visible and marked, so you can see exactly what the unlock opens before you spend anything. PRIVACY Lockana collects nothing and sends nothing. No ads, no accounts, no tracking, no analytics. All 1,386 words ship inside the app and nothing is ever fetched over the network — the only network use is the App Store purchase check, which happens inside Apple's own software.
