About this app

Problems of traditional learning methods
Many proficient Japanese speakers have often learned the language in a country where it is spoken. Our left brain is responsible for language processing, while our right brain processes images. Typically, when we see an image, our right brain reacts first. Traditional learning methods can create faulty language structures because they rely solely on the left brain for memorization through language alone

Key features of Lockscreen Japanese Dictionary
The Lockscreen Japanese Dictionary engages both the left and right brain to learn Japanese vocabulary. This allows you to recall both 'car' and '車' simultaneously when you see a picture of a car. This learning method provides a similar effect to learning the language in a country where it is spoken

Lockscreen memorization
Words are displayed on the lockscreen so that you can learn Japanese every time you turn on your phone.

Quiz alarm
Receive quiz alarms at your desired times to take quizzes. You can choose the word lists at your preferred level and also review your learning statistics.

Choose the level of vocabulary
Japanese vocabulary is sorted into different levels, from beginner to advanced, to match your proficiency.

Example sentences
The example sentences provided are written by native Japanese speakers and are useful for real-life situations.

Personalized Vocabulary List
Create a personalized vocabulary list to focus on words that are hard to remember or commonly mistaken.

Hide Memorized Words
Utilize the word hiding feature to strike out words that have been memorized, preventing them from appearing again.

Automatic Learning
The slide show feature is an advanced feature that can be used to automatically memorize words.

Takes over the lock screen the moment you open the app with an "Unlock!" button and ads. Prevents you from pressing back to exit (the lock just shakes) you have to press the middle button to get to the proper lock screen. On top of this there is always one notification that can't be cleared. Uninstalled right away because I didn't want this app to mess up anything else on my phone. DO NOT GET THIS APP.

Jacquiline Robayo 고객님, 안녕하세요? 소중한 리뷰 감사드립니다. 고객님의 일본어 암기에 도움이 되었다면 저희는 만족합니다. 사용 중 불편하신 점이나 개선할 부분이 있으면 언제든지 연락해 주시기 바랍니다. 일본어 단어 퀴즈가 포함된 앱도 출시했으니 많은 사랑 부탁드립니다. ^^ 감사합니다. ( 사람이 전부다. 와포일동 드림 )

you need some way of comparing the definition of words between languages and the option of it not using the battery until you open the app. also the writing practice needs to show stroke order for the kanji. 🇯🇵🇺🇸
