About this app

The world’s first AI-based English vocabulary builder app. If you are serious about your English, you will fall in love with WordUp. It is the smartest way to perfect your English, and learn every word that matters while enjoying the process!


Vocabulary Builder:
Vocab builder feature in WordUp utilizes advanced algorithms to expand vocabulary and improve English skills. It recommends a new word each day based on your current knowledge, allowing you to gradually enhance your language proficiency. By incorporating daily words into your learning routine, WordUp ensures steady and consistent growth in your vocabulary.

Knowledge Map
WordUp helps you build a map of your knowledge by identifying the words you know and the words you don't know. It helps you learn new words by identifying the gaps in your vocabulary and suggesting the most important and useful English words to focus on. By incorporating daily vocabulary and tracking your progress, the Knowledge Map enables you to steadily increase your vocabulary and enhance your understanding of English words.
All 25,000 useful English words are ranked in the order of IMPORTANCE, and USEFULNESS, based on how often they are used in real-world spoken English (extracted from thousands of movies, and TV shows).

To actually learn the words that you discover in your Knowledge Map, WordUp gives you everything you need, and more! From word definitions and pictures to tens of entertaining examples from movies, quotes, news, and more. So you get a good feel of how to use each word in context.

Multilingual Translations
There are also translations in more than 30 languages including French, Spanish, German, Arabic, Turkish, Persian, ...

The daily reviews then kick in. Like flashcards, the words will come back with games and challenges until you master them. It's called Spaced Repetition, and it's scientifically proven to help memorise them forever!

WordUp is unlike any vocabulary builder app you've seen before. It is not another dictionary app, although it can be used as an English dictionary too.

Suitable for Various Users:
WordUp's novel approach to language learning and expanding your vocabulary will leave you feeling confident and empowered. Whether you are new to English, are preparing for an English exam (IELTS, TOEFL, etc), or are a native English speaker, you will find WordUp helpful and entertaining. Just give it a try and see for yourself!

I love the app, I have recommended it to my friends and unlocked unlimited access to examples. However, after my phone's system crashed I had to install all apps back. I logged into my account and WordUp saved all my words, but I have limited access again. What can I do about it? Also, translations in cards are shown in alphabetical order, it would be very helpful to be able to also sort them by relevance. Thank you!

It was a great app. However, not a long time ago, the app changed and not for good. Whith every single update they try to find a way to make you pay. Instead of adding some new features in subscription, they cut off everything that was free and crucial in the learning process. They blur pictures, limit and then completely remove examples and videos. And now, they limit amount of word per day by introducing "heart system". It is like a cheap mobile game now, which only interest - your money.

Dear user, our free users are still provided with a wide range of options. They are granted access to the entire collection of 24,000 words accompanied by audiovisual content

Great idea. Very useful, not boring, with tons of life samples and context. Games with words also are fun, so, I recommend it. Previously I was admired by this app, it was really useful. But ad is really, really annoying in free version. Price for pro version, in another case, is incredibly high for Russian market: 1/30 of medium wage for month subscription. Sorry, guys - you are great, but not for me :'(
