  • Today's World - It Has Changed

    by dlvillard

    Progress is usually a wonderful thing, but in some things it can be very damaging. Vocabulary and spelling seems to be so trivial in the scheme of things in today's world. When was the last time you read an article or letter that a writer made an effort to use proper grammar and spelling? Is this the writers fault. Maybe or maybe not. Today, it just appears as if it's not important. Dictionary.com is a great application and is trying to help all of us to improve ourselves. I certainly need all the help I can get.

  • by Laila

  • Go To Dictionary App

    by Macfan608

    Love they Word-of-the-Day feature!

  • The Best

    by LadySin

    I can't live with out it, I'm learning new words every day, and also I learn how to pronounce them as well as spell them, you'll be surprise at what this app has to offer . I Luv It.

  • Thesaurus not so great!

    by Huff60

    The thesaurus seems no better than average! Some of the synonyms don't even seem to apply. I have googled and found better words, however if you need a quick app this is the one.

  • Dictionary

    by Barefootnot.com

    Excellent app! It's like having an entire dictionary and thesaurus in your pocket! I like the feature that allows you to hear the pronunciation of words.

  • Works terribly offline

    by mg94c18

    This app works terribly without wifi connection. I can't access the search field because it keeps jumping from one "network is required" to another, without the ability to reach search screen again.

  • 1 Star for being needy

    by freejayCDCS

    Hate the interruptions asking me if I love the app. It's a dictionary!

  • I dont like it

    by juanvillarreal

    it doesnt work offline

  • Word origins now need internet

    by Jacob Spaulding

    This app is one of the most important ones on my phone. And it worked perfectly until it was overhauled. Now the word origins require the internet. The primary thing that makes this app superior to Other dictionaries is it's offline access. ( I read and contemplate words most frequently in the subway). I will return my review to the five stars the app should be getting when this massive blunder is corrected.

  • wldy1005

    by Wanda Youpee

    pretty reliable. useful app

  • Dictionary review

    by Papa Fred 123

    I love this app, every time I come across words I don't know, a dictionary is at my finger tips. Word of the day is also nice feature, I try to keep up with it most of the time

  • Good

    by Steelersfan13


  • Dictionary

    by hp71user

    The inability to defeat the Word of the Day feature that delays access to word entry is telling of this app - very poor quality and performance.

  • Good wordy fun

    Love the word of the day. This is definitely my go to tool for fun with words.

  • My go-to-first reference

    by Amari.enti

    I use this app almost daily. It helps me overcome my ability to confuse spell-check, makes me sure of proper word usage, increases my vocabulary with word of the day, and has never crashed!

  • Best one

    by NardiCollege

    I use this one even thought, I paid for another one. A lot of words. You can see the history too to recall and learn the new words. I love this one.

  • Great App

    by JMBTX

    I reach for this App whenever I come across a word I don't know. Rarely, if ever, has it failed me.

    by Sldamron

    I use it to fill letters to my son in jail, he also enjoys it. I write twice a week and the letter that goes out on Sunday is all from your app and one other that also has quotes and word puzzles.

  • Excellent app

    by Toogie930

    Like the word of the day, ease of use, and ability to hear the proper pronunciation of the words. I had a little trouble with the app a while ago shutting down when I tried to open it, but appears to be fixed. No other issues before or since.

  • Best Dictionary App

    by Thadie2.0

    This app just keeps getting better. I had several dictionary apps, some more expensive than this one, and this is the best one. I have since deleted all of them but this one. I just wish I found this one first. I use it every day, several times a day. Love it!

  • Dictionary

    by Bender81

    This is the best one if ever used

  • I LOVE IT!

    by Aid33

  • Student

    by kramarista

    Nice apps. Very useful, lots of extra.

  • Great reference…

    by dannerville

    With all the additions, quite costly by app standards. More interesting than the Merriam Webster app.

  • Love it

    by MSprenger.2014

    I use this app every single day. As a kid, I read the dictionary when I could. As an adult, dictionary.com is always available. Best dictionary app!!

  • Great app!


    Love using this app every time I have a word question. Fast.

  • Cool app

    by Disaster Geek

    Love the word of the day push!

  • Perfect

    by CreateJp

    Good stuff

  • Messages feature useless

    by Angel75c

    The messages feature keys an alert number on the app icon, but when I select a message to read the app just gives a blank screen or shows the last searched word. Needs text sizing This is a very nice app but this app needs the font size to be user adjustable.

  • Love it!

    by Diction Addiction

    I use it everyday for everything. The most useful app not only for school but for life!

  • Xerces

    by jeremiah_w

    One of my most used apps!

  • Meh

    by Fritz_III

    The interface is way too distracting. Too much in your face. It makes me long for the old-fashioned books that present what you're looking for without screaming at you.

  • Great except for landscape switching problem

    by thecoast

    Great app. Except for not being able to automatically rotate to portrait if locked in landscape. You have to close it down and restart it after switching to portrait. It would be a 5 star app if they could figure this out.

  • Dictionary

    by Cabrrtt

    Excellent program!!!

  • Excellent!

    by Matt_H8

    Great interface, great features, and I love being able to tweet definitions. Definite download.

  • Supadupa

    by BuddyPat

    Great app if you love words - its not just a dictionary. Love the Spanish words too!

  • Must have app

    by Chris314159

    This is a basic must have app!

  • Everything that Webster isn't!

    by !ntelecto

    As far as dictionary apps go, this one is by far the most prodigious. I use it regularly and it is an invaluable resource for today's modern student of English language and literary studies. My middle school language arts students love this app!

  • Wifi

    by Gdrrwsdchvjofrfvjk

    I love having dictionary.com at my fingertips even when I can't get a wifi signal.

  • Use it all the time! Love it.

    by Crazy cool app

    Smart, fast, easy, helpful.

  • Great App

    by Raheemmaliki

    I find myself opening my trusted dictionary app at least once a day.... Great app.

  • I Love It

    by Camster11

    I use Dictionary a few times each week to make my writing more precise. I rely on it!

  • by Juicyfern

    I just find it really aggravating that after paying full price for this app (that I do love and use daily) I have to pay an extra fee to use their voice search. But actually I just realized while typing this that I can just use the voice search on my keypad lol. But still shame on this dictionary app for being money hungry! Seriously if I was to buy all their extra features I would be broke.

  • A Must Have App.

    by OSpv

    This is a very handy application. I use it all the time.

  • Great Dictionary !!!

    by Joseph Dewilde

    I am an avid reader do this dictionary is of great importance to me. The fact alone that is has the voice feature is worth 5 stars. Thesaurus, example sentences and the option to save favorites is well worth what I paid for it. The only thing I would add is the ability to somehow intergrade it into the iBook app or make it more easily accessible while using multiple readers.

  • Translator does not work

    by Ramy El-Meligy

    Translator is s**t, needs serious work, see e.g. Google

  • Great App!

    by Seekcolor

    Words are great. This app is great.

  • Great App

    by Daniel Porreca

    A must have for the iPhone. I use it on a daily basis.

  • It's good

    by streakin667

    I like the word of the day in my notifications but can I have the definition too instead of having to open the app?

  • Top notch

    by Ziggy-Stardust

    Great app, love the word of the day!

  • Greatest dictionary

    by AJpatent

    Love the completeness and organization especially the list of prior lookups. It reinforces memory by forcing you to recall.

  • Incredible, amazing!!!

    by fronton-KJV


  • Must have

    by Muttiblus

    One of my top 5 apps.

  • Nubby

    by bubby81

    I use this dictionary all the time it's the best.

  • Favorite dictionary app

    by Ulmanor

    I've tried a few dictionary apps, and this is the best I've found. For someone who likes to look up words independent of working on a note, it's convenient to have a standalone app, and the dictionary is larger than the others I've tried. The GUI and stability issues of past versions seem to have been resolved now with a more native interface. My one complaint is that one needs a network connection to view etymologies, but that's usually not an issue. Overall, this is the dictionary to have.

  • Used every day!

    by NatureGirl4evr

    Paper dictionaries cannot pronounce the word for you! Love being a click away from the thesaurus. A writer's best friend!

  • I use this app on my MAC

    by bootspur

    I really appreciate the app it has bailed me out many times...That said I used to be a premium customer, but can no longer justify the current cost @ $40.00 per/yr.

  • Good App!

    by RajC1

    I have purchased all the In-App extension. But I expect that there should NOT be any further payment expected beyond this.

  • Love this dictionary!

    by Evelyntax

    Use it all the time when reading & need definition. Also just for individual words meanings & pronunciation. Great book.

  • Helps win discussions

    by Bill J

    My wife and I were high school sweethearts. But our understanding of words is different. She won't believe me until I reference dictionary.com.

  • Excellent

    by GRBSMB


  • Otherwise five stars

    by Christopher Fernandes

    Please don't bug me to rate, otherwise 5 stars.

  • Excellent App

    by Katjah4405

    Love the Word of the Day feature!

  • Helpful!

    by IowaHawk22

    An English major's idea of fun! DD

  • Awesome!

    by Planbjr

    I'm smart now! Hahah

  • One of the better apps

    by AROWP

    Provides a simple, painless way to insert additional words and their understanding into your vocabulary

  • Very helpful

    by Chilpancingo

    I really like the app because it allows me to look up words, meaning and it also has a thesaurus. Also, for a non-native English speaker is good to have the pronunciation. Although, the only down side is that it does not include verb tense. That would be really helpful, specially for irregular verbs.

  • GREAT!!

    by nedrod

    I use this app multiple times every day. It is indispensable.

  • Great app!

    by .................,

    So useful

  • Not so sure now

    by IBCoco

    New update now puts Word of the Day on the opening screen. Don't like that. If want it, I will find it. Mostly I want to look up my word! What am I doing wrong?

  • Love this App!

    by Ruby Haze

    Very handy to have on my desktop, and phone! Really appreciate the audio pronunciation of words. This would also be a great app for students as well.

  • Use it everyday

    by Tahevol

    I use this and the companion thesaurus daily. We all know the concept of the dictionary, but this is simple to use and reasonably comprehensive. I've had it well over a year and have never run into technical glitches. I like the pronunciation function that says the word if I don't know the proper pronunciation.

  • Dictionary

    by dickbowman

    Great daily enjoyment. I hate to miss a day, but I can always go back. I haven't become familiar with all the new features such as the Thesaurus , but that will come in time. The additional dictionaries are very useful.

  • A fine wine that has gotten better with age.

    by Fenavian

    I have been a dictionary user since release, and this is one app that has gotten better with age. While it would be nice if they put out specials where you can buy all of its (very useful) DLC into one affordable package, it still is worth every penny. Even if you didn't purchase any DLC, you are getting a robust app that outstrips other dictionary apps. And what I like about the DLC is that you just buy what you need. But each DLC makes very significant and positive additions to the app, so it is, at least, worth looking in to. To sum up: A great app that keeps getting better. You don't have to buy any DLC for this to be a great app, but the DLC is worthwhile as well. Enjoy.
