Vocabulary Apps (2026): 10 Apps to Learn New Words Daily

Most people don't need a bigger dictionary. They need to meet the same useful word three or four times in a week, in different places, until it turns up in their own speech without effort. That's the job a good vocabulary app does well.

The apps below are listed alphabetically and in no particular order, and each description comes from the provider's own website or app store listing, read this week. If you'd rather learn through play, my round-up of word puzzle games for your brain is a lighter way in.

Vocabulary apps at a glance

I checked the free plan column on each provider's own website or app store listing, as of Oct 2026. Yes means the page names the app, an account, a plan or a version of it as free. Trial only means a time-limited trial. Not stated means the page I read named neither, even where there's a button inviting you to start or a store download button, so check the provider's own page before you sign up.

What the national curriculum says about vocabulary

The Department for Education's English programmes of study list acquiring a wide vocabulary as one of the core aims for every pupil. They also say the quality and variety of language pupils hear and speak are vital for developing their vocabulary and their understanding for reading and writing.

That second point matters for adults too. A word you've only tapped on a screen is a word you'll recognise, not a word you'll use. The apps get you to the recognising stage quickly; speaking and writing get you the rest of the way.

Word of the day apps versus adaptive learning apps

Word of the day apps send you one new word each morning with a definition and an example. They're easy to keep up and pleasant to read, but they don't check whether you remembered yesterday's word.

Adaptive apps test you, track which words you keep missing and bring those back more often. They take a little more effort each day, and they're the better choice if you're preparing for an exam or learning English as a second language.

Learners who translate as they go may also wonder whether DeepL is free.

A ten-minute routine that makes new words stick

1. Learn or review a handful of words in the app.
2. Pick one word and say a sentence with it out loud.
3. Write that sentence in an email, a message or a notebook.
4. Look for the word in something you read that week.
5. Let the app bring it back for a quick test a few days later.

Learners who want the words to land on paper as well as in the ear can see a roundup of spelling practice apps.

Signs an app isn't doing its job

• You recognise words but never use them. Add the speaking and writing steps above.
• Streaks matter more than learning. You're tapping through to keep the count going.
• The words are too obscure. Swap to an app that ranks words by how often they're used.
• You've stopped opening it. A daily notification at a better time often fixes this.

Do you make vocabulary, dictionary or word learning apps? Tool makers can ask to be considered for a featured place on this list.

My plain advice on vocabulary apps

Pick one app that matches your goal, give it ten minutes a day for a month, and use every new word out loud at least once. That simple habit beats collecting five apps you never open, and you'll hear the difference in your own writing within weeks.

If you like a daily brain teaser alongside your words, the puzzles in games like Wordle make a good five-minute pairing.

Frequently asked questions

Is there a free vocabulary app?

Several apps on this list name a free version or free use on their own page, so check the free plan column before you download.

Which vocabulary app is best for English learners?

Apps that build a personal map of the words you know, and test you on the gaps, tend to suit English learners best.

Do vocabulary apps help with exams?

They can, especially adaptive apps that keep testing the words you miss, but pair them with past papers and real reading.

How many new words should I learn a day?

A handful you'll use beats a long list you won't, so start small and keep the habit going.

Are vocabulary apps good for children?

Some are built for classrooms and teachers, so check the age range on the provider's own page.

Can I learn vocabulary offline?

Some apps on this list work offline, including a dictionary app with full offline definitions.
