How to Choose the Right Dictionary App

There’s a myriad of dictionary apps out there. So it can be a struggle to choose the app that’s right for your needs. Use this brief guide to aid you in your search for the perfect dictionary app:

Sources of Definitions

If you are looking for the right meaning of a word, it’s worthwhile to know where a dictionary app sources its lexical meanings from. For example, if the definitions come from online submissions, then the app might not be very good.

Ideally, find a dictionary that uses definitions from established sources, like the Oxford dictionary or the American Heritage dictionary. It’s common for most apps to use multiple sources for word meanings.

You can read the most established definitions for complex English words from a dictionary app with good sources. Otherwise, you might not be able to rely on the definitions.


English dictionaries sometimes specialize in giving meanings in a subfield or genre. Are you looking mainly for legal, medical, or idiomatic terms?

If so, you might need specialty app like a medical dictionary or a slang dictionary. Meanings for certain terms typically not used in general written English only appear in these specialised dictionaries.

Slang words in spoken English rarely appear in dictionaries. That is, unless you choose a special dictionary for slang meanings.

So think carefully about what you need the dictionary for. Then choose the best dictionary type for your requirements.


Dictionaries have a surprisingly large number of features, which you may not initially think you need. For example, the best dictionary apps show a “Word of the Day,” so you can learn a new word every day.

Other such features include voice search, pronunciation aids, and searchability functions. The latter is important when you want to look up words with spellings you are unsure of.

Do you want to use the phone’s camera to scan a word and look up its meaning? Cool features like this can vary from app to app.

You can do a side-by-side assessment of such features before choosing the app you want. Remember, these features amazingly enhance the use of a dictionary app.


Obviously, the dictionary app you need would have to be compatible with the operating system on your phone. Not all apps are cross-platform compatible.

While a lot of apps are available on both Android and iOS, keep in mind that the functionality of these apps could change between the operating systems. A popular Android dictionary app may look slightly different on an iPhone.

It’s best to choose a top-ranking app based on specific platforms. Otherwise, you might have to deal with annoying compatibility issues.

Internet Connectivity

Do you want your dictionary app to be available even when the phone is not connected to the internet? It’s a seemingly simple feature, but some apps are not available without the internet.

Most of us would prefer to have a dictionary app that works with or without the internet. You can look for offline dictionary apps to benefit from this feature.


Unfortunately, not all dictionary apps are free. Most dictionary apps, especially branded apps, charge a fee.

Fees are mostly subscription-based. You might be able to get away with a one-time free.

While free apps are desirable, subscription-based apps may offer more features. So it’s worthwhile considering the cost as well.

In Conclusion

Getting a dictionary app can be a little complicated because of the sheer number of choices available. The above article points out:

  • The best dictionary apps available for various platforms
  • What you need to know before installing a dictionary app
  • Tips for choosing between dozens of options available

Any one of the above mentioned apps and programs will suit business and home needs adequately.

Most of the above software is free to use. However, if you are willing to pay a small subscription fee, you can squeeze more out of these apps.
