About Lockscreen Japanese Word Alarm

Always memorize Japanese words with pictures and quiz alarm on the lock screen

✔ 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

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