About Lock&Learn Japanese: JLPT
Walk into the JLPT already knowing every word on it. Lock&Learn Japanese puts real JLPT vocabulary on your Lock Screen and Home Screen widgets, the screens you already check a hundred times a day. Each word arrives with its kanji, reading, meaning, and an example sentence you would actually say, so the language settles in through your day instead of in one long sitting. No account. No streak anxiety. Just the language, arriving quietly. HOW IT WORKS - Add the widget to your Lock Screen or Home Screen - A new word appears each time you glance, rotating throughout your day - Tap any word for the full entry: kanji, kana reading, meaning, and an example sentence with its reading and translation - Move through the JLPT levels at your own pace THE FEED Open the app and keep going: your deck as a full-screen feed, one card at a time. Tap to flip a card, swipe up for the next word, swipe left to save it, swipe right when you already know it. The scroll you reach for anyway, made of vocabulary. QUIZ MODE One tap on the bolt and the feed becomes a quiz, dealing your words back to back. Word rounds ask what a word means. Sentence rounds blank the word out of a real sentence. Listening rounds ask by ear: nothing to read, just the word spoken aloud. Getting one wrong never affects your progress. Choose whether rounds draw from the words you have glanced or your whole deck, and set each kind's clock, in Settings. A QUIZ ON YOUR WIDGET, TOO Prefer a challenge before you even unlock? Flip the widget to a question. It shows you the word and asks what it means, then reveals the answer with one tap. A tiny test every time you check your phone. YOUR OWN LISTS Every word carries a save button. Tap it to keep the word, hold it to file the word into a list of your own: travel words, exam words, the ones that keep slipping away. Your lists live in the Library, ready before your trip is. YOUR PROGRESS A Progress screen in the Library counts the words you know and the words you have met, keeps your streaks, and fills one bar per level as you climb. A quiet answer to how it is going, with no dashboard in sight. BUILT ON THE JLPT The vocabulary follows the JLPT levels, the standard framework for learning Japanese, from your first N5 words up through the N1 vocabulary of newspapers and the workplace. N5 is free forever, the whole first level, no trial and no catch. When you are ready for more, Lock&Learn Japanese+ opens every level. MADE TO BE CALM - Notifications are off by default and always opt-in - Everything is stored on your device, nothing is collected - Save words with a tap, or file them into custom lists of your own - Beautiful, readable kanji in a classic type style Lock your phone. Learn Japanese anyway. Lock&Learn Japanese+ is available as a yearly subscription with a 3-day free trial, or as a one-time lifetime purchase. Payment is charged to your Apple Account. A subscription renews automatically unless canceled at least 24 hours before the end of the current period; manage or cancel it any time in your Apple Account settings.
