Learning English doesn't have to be expensive. Nor does it have to take a long time. With the right apps, you can progress in the language quickly, enjoyably and without spending anything. The key is to make good use of the time you already have.
You can learn while waiting for the bus, during lunch or even before bed. And the best part: you don't need books or traditional classrooms.

1# Duolingo
You've probably heard of Duolingo. And no wonder: it's one of the most downloaded apps in the world when it comes to learning languages.
The reason for its success is simple: it turns learning into a game. With each lesson, you earn points, advance levels and unlock new stages. All this with a fun and colorful interface.
But what really matters: does it work? Yes, especially for beginners and those who want to brush up on the basics in a light-hearted way.
The app covers vocabulary, grammar and listening comprehension. And you can study for up to 10 minutes a day and already feel the difference.
Want to start from scratch and not feel bored? Duolingo is a good choice.
2# Cake
Cake is an app that has grown a lot in recent times. And with good reason.
It teaches English through short videos with real lines from movies, series and youtubers. In other words, you learn how English is spoken in everyday life - with real expressions and natural pronunciation.
The difference lies in the practice of listening and speaking. You watch the video, listen to the sentence, repeat it out loud and compare your pronunciation with the original. It's a very practical experience.
Another plus point: the app is light, easy to use and completely free. You can even download the lessons and watch them offline.
If your goal is to understand English spoken by native speakers, Cake could be your favorite.
3# BBC Learning English
Want to learn English with reliable content straight from the source? The BBC app is one of the richest and most serious options on the market.
It was created by the BBC (the British broadcaster) and has lessons organized by themes, levels and learning styles. There are texts with audio, videos with subtitles and quizzes for practicing.
The content is updated every day and focuses on British English - which is great if you plan to take exams like the IELTS or travel to the UK.
Although it doesn't have as "pretty" an interface as other apps, the content is of the highest quality.
If you want to take your English seriously, it's well worth installing.
4# LingQ
LingQ is for those who already have a foundation and want to expand their vocabulary naturally.
The app works like a library. You choose topics you like (business, travel, series, politics, etc.), read texts with built-in translations and listen to the audios at the same time. Each new word can be saved for future review.
It encourages learning through repetition and real exposure to the language - which is how we learn our mother tongue.
The free plan has some limitations, but you can use it well. And the more you read and listen, the more your vocabulary develops.
For those who like personalized and less "schooly" content, LingQ is a great choice.
5# EWA English
EWA has become famous for offering classes inspired by series, films and books. The idea is to learn English the way you consume entertainment.
You can watch movie clips with subtitles, learn everyday expressions and even answer exercises based on the scenes.
Another cool thing: the app has a collection of English books adapted for different levels - from basic to advanced. And all with real-time translation.
The free part already delivers a lot. And if you use it every day, you'll notice rapid progress, especially in your vocabulary and listening skills.
If you learn best with visual stimuli and interesting content, EWA can be your ally.
6# HelloTalk
Want to practice with real natives? HelloTalk is a language exchange app that connects you with people from all over the world.
It works like this: you teach Portuguese to a native English speaker, and they teach English to you. The conversation can be by text, audio or voice call. All within the app.
What's more, you can publish short texts as if it were a social network. And other users correct your mistakes or interact with your content.
It's a very authentic way of practicing. No ready-made phrases - here, you learn how people really speak in everyday life.
The app is free and is moderated to avoid problems. Just create a profile, say you're learning English and start chatting.
Can you learn English with just an app?
Yes, as long as you have discipline and constancy.
Apps help a lot with vocabulary, grammar, listening and even speaking. But to really learn, it's important:
- Study every day, even for 10 minutes
- Repeat the words out loud
- Review the content from time to time
- Using the language outside the app (watching movies, listening to music, following English profiles)
The secret is immersion. The more contact you have with English, the faster you'll learn.
What's the best app to start with?
If you're a complete beginner: start with the Duolingo.
If you already have a base: go for Cake, EWA or LingQ.
If you want something more traditional: the BBC Learning English is a sure bet.
If you prefer to talk to real people: the HelloTalk will surprise you.
You don't have to choose just one. You can combine two or three, depending on your time and your way of learning.
What if I only have 10 minutes a day?
Yes, you can learn. In that case, choose a light app with quick lessons - like Duolingo or Cake. Use the time with focus. Avoid distractions. What matters is not how long you study, but how often.
And if you can, listen to English even when you're not studying - in the shower, in the car, during a walk.
