Learn a new language or improve your skills with a free mobile app

The Ultimate Guide to Online Learning at Home
The Ultimate Guide to Online Learning at Home

These free language learning apps will guide you through learning a language from start to finish, or help you sharpen language skills that you may already have.

Learning a new language with an app is particularly helpful because you'll always have those directions at your fingertips. Even a few minutes waiting for an appointment, or 15 minutes in the back of an Uber, gives you time to complete a lesson.

Whether you're learning a language to be able to order a meal on your next vacation, communicate with a friend in her preferred language, or to simply add a skill set to your resume, these apps are a great way to reach your goal.

You can use one to learn words and phrases in lots of different languages, including Spanish, English, French, Italian, German, Irish, Dutch, Russian, Chinese, and many others. Just check each description to see which app teaches what language.

Many of these apps also have free language learning websites that offer even more options. You can also use a language exchange website for more practice with real people. Another option is a translator website for one-off translation needs—some even support pictures and entire web pages.

We haven't included programming languages or sign language learning resources here.

Duolingo Android app
What We Like
  • User account not required.

  • Supports lots of languages.

  • Many ways to learn.

  • Lots of free lessons.

What We Don't Like
  • Lesson paths are sometimes hard to understand.

It’s really easy to get started learning a new language with Duolingo. Just open the app and then choose what language you’d like to learn to immediately begin the course. You don’t even have to create an account to start, but if you do, you can save and track your progress. 

This app begins by using text, pictures, and audio to help you learn a different language. The idea is to associate the sound of the translation with the visuals of the text and pictures, and then have you manually translate the audio back into your preferred language to help reinforce the new words. 

Every section you complete moves you forward to more difficult tasks, to build on your vocabulary and sentence structure. You have the option of testing out of several sections at once if you’re familiar with the language, and Duolingo will adapt the questions based on how well you do.

Languages You Can Learn: Spanish, French, German, Japanese, Italian, Korean, English, Chinese, Russian, Arabic, Portuguese, Hindi, Turkish, Dutch, Latin, Swedish, Greek, Irish, Polish, Norwegian, Hebrew, Vietnamese, Hawaiian, High Valyrian, Danish, Indonesian, Romanian, Welsh, Scottish Gaelic, Czech, Swahili, Hungarian, Ukrainian, Klingon, Navajo, Esperanto, Finnish

Duolingo works online through the website, as well as via the app for Android, iPhone, iPad, and Windows 11/10.

Memrise Android app
What We Like
  • Unique teaching methods.

  • Learn several languages.

  • Upgrade options.

What We Don't Like
  • Must make a user account.

  • Unfriendly website design.

Memrise is another free language learning app. It’s not as smooth as Duolingo, but it is easy to work with, supports offline courses, and lets you learn a massive number of languages. You can start off simple or skip all the way through to more advanced lessons.

Something unique about Memrise is how it teaches you new words and phrases. Words are put into sentences with similar sounding words from your preferred language to help build the connection for remembering them. You'll also sometimes see multiple images that you can scroll through that overlay the foreign text with a recognizable image for added association.

Another method Memrise uses is to teach you a different language is by mixing up the translations. This way you learn a few new words at once, and then you keep learning them over and over again in a different order to ensure you know them before moving you through to the next round.

Languages You Can Learn: English, French, Spanish (Spain and Mexico), German, Arabic, Korean, Japanese, Japanese (no script), Turkish, Chinese (Simplified), Dutch, Italian, Swedish, Portuguese (Portugal and Brazil), Russian, Norwegian, Polish, Danish, Icelandic, Mongolian, Slovenian, Yoruba

You can use Memrise from the Android, iPhone, or iPad app, as well as online through a web browser.

  • Several learning modes.

  • Built for travelers.

  • Unique features.

  • Supports lots of languages.

  • Multi-platform support.

What We Don't Like
  • Learning method seems out of order.

Rosetta Stone is a professional-grade service for language learning, but they offer a free app meant specifically to help travelers learn basic words and phrases.

There's also a phrasebook with basic words and words related to restaurants, hotels, and getting around—all very useful for someone traveling. You can buy more phrasebooks if you like, such as words related to shopping, colors, emergencies, and currencies.

Google Translate

Google Translate Android app
What We Like
  • Helpful translation methods.

  • Great for quick translations.

  • Works with lots of languages.

  • Also run on the web.

  • Updates frequently.

What We Don't Like
  • No step-by-step lessons.

Most language learning apps teach you a language through exercises and progressive steps, while Google Translate simply tells you how to write and speak anything you run through it.

You can translate text, handwriting, and your voice with Google's translator app. This means you can enter text manually, draw the text, or speak it to convert it into the target language. You can even save your favorite translations so you can refer to them quickly whenever you like.

Google Translate may not be like these other apps, but it's certainly a great tool if you're stuck on a specific word or phrase, or if you prefer to target your learning to particular phrases and sentences only. It can especially prove to be beneficial if you're speaking with someone that doesn't know your language

It can also translate even when you don't have an internet connection (just be sure to download the language pack ahead of time).

Another feature that makes this app a must-have if you're traveling is instant translations. Available for only some languages, it's a type of augmented reality that uses the camera on your phone to translate, in real time, any text you point your camera at, including foreign text displayed in a menu, written on a sign, etc.

Not all translations can be spoken back to you, but all translations can be displayed as text.

Languages You Can Learn: Japanese, Dutch, Danish, Greek, Bulgarian, Swahili, Swedish, Ukrainian, Vietnamese, Welsh, Chinese, French, Hungarian, Korean, Czech, English, Persian, Latin, Bosnian, and dozens more

Google Translate runs online and from iPhone, iPad, and Android devices.
