📝 About this app

We've updated a ton of content and features.

We'll be updating more content more frequently in the future.
====================================

★A miracle vocabulary learning app. Just turn on your phone and it'll start studying automatically!

The foundation of English learning is vocabulary memorization.
The foundation of vocabulary memorization is repetition. You memorize words by seeing them often.
But you don't have time to study English.
But how often do you check your phone?
That's why we developed "English Vocabulary as Soon as You Turn It On"!
Study one word every time you turn on your phone!

You probably check your phone several times a day. Every time you do, even if it's just by accident, look at the words.
And before you know it, you'll be the ultimate vocabulary master!

★ You can study over 30,000 English words and vocabulary lists, divided into levels, for TOEIC, TOEFL, CSAT, SSAT, SAT, elementary, middle, and high school English vocabulary, and civil service exam preparation.

★ TOEIC prep questions (vocabulary/grammar) are as simple as the actual words themselves! You can study in your spare time. (Explanations are also provided.) Just solve these questions a few times and you'll master vocabulary and grammar!

★ We also provide English expressions and sentences commonly used by locals. If you practice conversations in your spare time, you'll be fluent in English in no time.

★ Recommend this app to your friends! The more people you share it with, the more vocabulary lists and new features will be added.

★ We're making it even easier to study than an English dictionary.

[Useful Tips]

◎ You must press the [Confirm] button to see the next word. Pressing the Back or Home button will continue to display the same word the next time.

◎ What if the pronunciation of a word is too low?
>>> Try increasing the 'Media Volume' instead of the ringtone volume!

◎ You must press the [OK] button to display the next word. Pressing the Back or Home button will continue to display the same word the next time.

◎ What if the pronunciation doesn't work at all? (The TTS engine that reads pronunciation isn't properly installed on your phone.)
(1) Download the "Google TTS" app from Google Play.
(2) Go to Settings > Language & Input > Text-to-Speech Options (TTS Output). Select the Google TTS (Text-to-Speech) engine as the default engine.

◎ What if Pantech (Vega) users can't hear English pronunciation?

This issue is caused by the "English-non-supported TTS feature" built into the Vega being activated first.

When you go to TTS output on your Vega phone, you'll see Diotts for Vega and Google TTS. Vega's built-in TTS is preferred. However, Vega's built-in TTS doesn't support English. Therefore, you need to disable Vega's built-in TTS feature for Google TTS to function properly and produce pronunciation.

** How to disable Vega's built-in TTS***
Go to (Phone) Settings - Application Management - All - Find the Diotts for Vega (or VegaTTS) app. - Disable - Click OK to enable pronunciation listening.

(▲Thanks to 'Ryu ㅇ주' for sharing the Vega phone solution in the review.)

[Special feature of English Vocabulary on Turn On]
You can automatically see English vocabulary on the lock screen, like an alarm.
Just like an alarm goes off in your daily life, it automatically reads English vocabulary and conversations as soon as you turn it on!
Study English easily by relying on the English vocabulary as soon as you turn it on and achieve your goals.💜
