How Do Vocabulary Apps Help You Learn English Words Faster?

  • They usually have the relevant vocabulary to suit your needs. English learners have diverse needs. For example, a student of business English won’t benefit much from studying engineering or medical vocabulary.
  • They often feature interesting and fun games. You may not remember much if you memorize a bunch of words from a list. But if you encounter those same words in a game, you can better associate them with pictures or events.
  • They encourage you to use them daily: Practice makes perfect. These apps come with daily reminders and motivational messages so you have an incentive (reward) to learn and do your English vocabulary exercises regularly.
  • They constantly give you new words to learn. Most of these apps have a ton of vocabulary words. Whether you are a beginner, intermediate or advanced learner, most of these apps are worth having for their vocabulary banks alone.
  • They often have multiplayer options, so you can learn and compete in a study group. For some people, group study works better than studying on their own. Many of these apps allow you to compete with friends or have a scoreboard that allows you to see how you are doing. This makes you more invested in the game and helps you learn faster.
  • They let you practice English wherever and whenever your want. Even if you are on the bus or on lunch break, you can easily learn a couple of new words with the best vocabulary apps for English learners.


When using these apps, try to pick up English phrases and words relevant to you and review them now and then. Look for opportunities to use these newly-learned words often.

Even if you make mistakes, learn from them and keep at it. As long as you are passionate and disciplined about your learning, you can grow a beautiful English word garden!
