App Description
English words you encounter every time you turn on the lock screen!
🔵 English Study Begins the Moment You Turn on Your Phone
Do you need to memorize English words but find it difficult to set aside time for studying?
"Hayword English Vocabulary" is an English vocabulary app that transforms the brief moment you check your phone's lock screen into English learning time.
You don't have to go out of your way to open a vocabulary book or launch the app every time. Check the word and its meaning, and naturally learn the words by listening to the pronunciation every time you turn on your phone.
It is okay if you don't study for a long time at a time.
Words you encounter briefly, frequently, and repeatedly every day will become familiar words before you know it.
───────────────────
🟠 Repeat Naturally on Your Lock Screen
You check your phone's lock screen several times a day.
Just by checking a single English word during that brief moment, you can continue consistent repetitive learning in your daily life.
✅ Learn without launching a separate app
✅ Check words and meanings on the lock screen
✅ Study effortlessly even in short bursts
✅ Utilize your commute, school commute, or breaks
Instead of creating new time for English study, try turning the time you are already using into study time.

🟢 Check words and meanings quickly and easily
We have designed it so you can check important information at a glance, rather than relying on complex explanations.
Quickly review English words and their key meanings, and listen to the pronunciation immediately if you are curious.
