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 this app, it really honors its slogan "Words that matter" I have tried to increase my vocabulary and learn some advanced words in many ways, but most of the time I would just end up learning complex words that I would definitely not use. With this app I have learned lots of word that I have actually encountered and used. The only complain I have is that unfortunately the free version doesn't allow us to learn phrasal verbs or idioms... But leaving that aside, it's perfect 4⭐

I REALLY enjoy the app, but the iPhone version. The Android one, for some reason, cuts the bottom line of the app, and I just don't know whatever is written down there. Edit* They might have fixed the crashing issue on the beta version, but honestly, that version feels too crampy and tight to me. I can't imagine how hard the work is, but this is an honest opinion. *Still no fixing about the bottom line to this date.

Not only the idea is great, but the coding itslelf is quite good too! these people are working hard all the time and I simply love this app so much. I recommend to add a possibility too connect with other people so you can compete on your knowledge. I learnt English with my friends during normal conversations. My biggest problem is my vocabulary. this app is slowly but surely solving that issue! Keep up the good work!
