It's very helpful to me

I’m nothing without it, especially reading advanced scholarly study books.

I am training for the ISEE and the games really help me prepare and they are fun! Really recommend to just generally become smarter. The true or false also is really helpful!

I love this app. Everyday I can find a new word, a deeper meaning, more clarity of understanding

It’s good but does not explain well enough but still that’s just onr\e thing so I would give it 4 stars
ANG3LJ4DE • Jul 26, 2026 ★ 5
I like it, its smooth and its easy to use.

Why bother using this app when there are other options with more words and no ads. The camera can’t even read text. Terrible joke in 2026

Not only are the words perfectly described, the app also gives you the pronunciations of the word you need to hear and they use it in a sentence to use it as an example. Not to mention the quizzes and games, they’re incredibly fun and challenging. Truly outstanding.

By putting ads in this application you spit on the memory of the brilliant Noah Webster. May your ancestors look upon you with shame.

My favorite dictionary app. It even has fun word games. Kudos to whoever writes up the “Did you know?” section, particularly the one for “stalwart.” The very last sentence made me smile.

Being able to consult an online dictionary is great. However, after a word is entered, this app sometimes traps the unsuspecting user in a spam freeze, making it impossible to go either forward or back without clicking on a full-screen ad. Even once in the ad, one sometimes has to close the app itself in order to escape.

Ever since google added their stinky AI overviews they full on overhauled the built in dictionary they used to have. I think that’s completely outrageous as the AI has been shown to inaccurately define many words and phrases. The dictionary app makes it easier to find the true meaning, origins, and usage of words and it has other great chunks of knowledge as well not to mention being fabulously up to date. Why is the likely most used website globally making us waste drinking water to find out what a word means???? In this day and age you have to be up to date on the truth and you have to make sure you know where to look!

This app is so good

Have used this in book form since I was in elementary school. You know when education was important and teachers goal was to teach without interference.

Ads every two clicks have made this app unusable

I do word of the day every day. I use for looking up words too!
EmLyssy • Jul 19, 2026 ★ 5
I have been using this app for 15+ years. It has everything you need. If you write, it’s a must. If you like to expand your vocabulary it’s perfect.

I love looking up words quickly on my Merriam-Webster app. I would say that almost daily I’m on the app and am happy with it. Another time I use the app is when my family is playing word games. It’s especially helpful. I’ve definitely learned new words and their meanings all the years I’ve been using the app. Thank you Merriam-Webster!
