About this app

Problems of traditional learning methods
Many proficient English 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 English Dictionary
The Lockscreen English Dictionary engages both the left and right brain to learn English vocabulary. This allows you to recall both 'car' and 'automobile' 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 English 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
English vocabulary is sorted into different levels, from beginner to advanced, to match your proficiency.

Example sentences
The example sentences provided are written by native English 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.

A very good idea app for self teaching English. Viewing pictures, reading examples that make us feel better memory the word. It has some good features like sound, graphics, examples, videos, pin the word but missing one thing that I would like to see, the kind of that word, it's a noun or an adjective, verb, adverb... Hope it could be updated in the future version. I don't rate it five stars (it should be) because it costs much money to update to no add version. But I will recommend this app.

Great App. But please allow selection of at least two languages in 'language for meaning' settings. I'm learning lots of new words in English but also want to know it's hindi word and using the extra language button everytime is very time consuming. It would be so awesome if you allow displaying of 2 languages on image card.
