7 Spanish Dictionary Apps for Your Smartphone That Are Hella Handy

The moment you realize you need a dictionary, it’s already too late.

Kind of like with toilet paper or a plunger.

Dictionaries are extremely important learning tools, but they’re often neglected by modern Spanish learners.

You’ve already got access to Spanish flashcard apps, learning podcasts and more on-the-go tools thanks to your smartphone.

So, why do you need such a seemingly archaic tool as a dictionary?

Why You Need to Download a Spanish Dictionary App, Now

The benefits of the traditional dictionary carry over the app form. Beyond that, dictionary apps have all kinds of additional functions that make them valuable to learners. The most important of these features? Convenience and discretion.

  • Convenience. You’re definitely too lazy to drag a big ol’ printed dictionary around with you everywhere you go. Dictionary apps have all the practicality of a typical printed dictionary, just with a little added portability, ease of navigation and convenience.
  • Discretion. I mean, when traveling you don’t want to stick out as a dorky tourist whipping out a dictionary on the street, do you? Now you can just glance at your smartphone instead. People around you will probably just think you’re texting, like everybody else in the world these days.

How to Use Your Spanish Dictionary App for Language Learning

  • Fill in the blanks. When you forget the word, look it up! It’s as simple as that. Sometimes you’ll just need some instant gratification so your conversation (or thought process) won’t shudder to a sudden halt.
  • Set a time limit. It may almost feel like you’d be cheating to break out the smartphone every time you forget a word. Well, you don’t have to do that. Let your brain struggle and flounder to recall vocabulary and grammar on its own. This teaches your brain how to go digging for important linguistic information. If you give up too quickly, you will no longer have this skill. That being said, you don’t have to be too strict about not looking up information. Give yourself a certain amount of time. If within, say, 2-3 minutes you can’t break through your brain-block, you can resolve to look up that pesky word.
  • Keep the brain train working. When trying to recall a vocabulary word—even if you’re alone—talk or think your way as close to the word as humanly possible. For example, if I were trying to think of the word “catnip” in English, I might try to describe it by saying something like, “It’s that plant stuff you give to cats and it makes them go totally crazy. It’s like a drug for cats…” Then, I’d just keep going around and around until I finally have the word pop into my brain, or until a conversation partner clues me in.
  • Always have a “word of the day.” Some of the dictionary apps reviewed below have a “word of the day” feature on their home screens or have a connected social media company profile that provides followers with daily vocabulary. If you don’t get one automatically, browse and select a random word every day. Copy down the word and its definition in a notebook and keep a running list.

In this post, we’re going to explore Spanish-English dictionaries and full-on Spanish language dictionaries. But before that, let me tell you about a place where you’ll get not just a Spanish dictionary, but an awesome language-learning program: FluentU.

FluentU takes real-world videos—like music videos, movie trailers, news and inspiring talks—and turns them into personalized language learning lessons.

Other sites use scripted content. FluentU uses a natural approach that helps you ease into the Spanish language and culture over time. You’ll learn Spanish as it’s actually spoken by real people.

FluentU has a wide variety of videos topics, as you can see here:


FluentU brings native videos within reach with interactive transcripts. You can tap on any word to look it up instantly. Every definition has examples that have been written to help you understand how the word is used.

Plus, if you see an interesting word you don’t know, you can add it to a vocab list.


Review a complete interactive transcript under the Dialogue tab, and find words and phrases listed under Vocab.


Learn all the vocabulary in any video with FluentU’s robust learning engine. Swipe left or right to see more examples of the word you’re on.


The best part is that FluentU keeps track of the vocabulary that you’re learning, and gives you extra practice with difficult words. It'll even remind you when it’s time to review what you’ve learned. Every learner has a truly personalized experience, even if they’re studying with the same video.

Start using FluentU on the website with your computer or tablet or, better yet, download the iOS or Android FluentU app.

In the meantime, let’s look at some Spanish language dictionaries. 

These are awesome tools for intermediate to advanced learners, who are constantly striving to become more completely immersed in the Spanish language. So, if your Spanish level is good enough that you don’t need direct English translations, and Spanish language definitions are sufficient for your purposes, then this is seriously a great way to go. It’s kind of like having a built-in thesaurus app, since you’ll come across plenty of synonyms while reading definitions.

If you’re not 100% sure you can handle so much Spanish in your dictionary, just give yourself a challenge and try this out anyway. You’ll probably surprise yourself with how much you’ll understand! Without understanding every last word in a word’s definition, you’ll still get a good sense of the word’s general meaning.

All right, I’ll tell you straight up—this one doesn’t come cheap. One reviewer called this the “Rolls Royce” of Spanish dictionary apps, and they’re onto something with that description. The layout, quantity and quality of content makes the old MW a clear cut winner in terms of dictionary apps. Do you need a seriously high-powered dictionary at your fingertips? Then you may want to download the 30 day trial, take it for a spin and see how this one works out for you. If you love it—which I suspect you will—it’ll be time to part ways with $25.

It will save your recently searched words, store lists of favorites, create vocab categories and deliver words of the day.
