    What a fabulous resource! Aside from instant definition access and lengthy lists of helpful synonymous terms via the thesaurus, the articles are also fascinating to the Natural Self-Educator and the Fanatical Linguistic Nerd alike. This is an excellent App.

  • Don’t Buy their add ons

    by earbuddude

    i purchased the rhyming dictionary as an add on and the purchase went through but i never got the download. i reported it as a problem to Apple, but they didn’t resolve it. and i contacted dictionary.com who also did nothing about it. so i am giving this app and their company ask.com 1 star and 2 thumbs down.

  • Educating

    by druseegirl

    I've increased my Vocabulary by using this App.

  • Where is the full site?

    by SeriouslyDave

    Why can't we get to the full site from our mobile browsers now? That always used to be available. It was fantastic. Now all we get is something that looks as incomplete as this app. Very disappointing. --

  • Great app

    by tumbleurbutt0ff

    I use this app because it has a sound option where it speaks the word to you. I know you can get definitions from iMessage but this allows you to see how it's pronounced which I find very helpful when wanting to apply new vocabulary words to my everyday language.

  • Me

    by GAJ Jeb n AMBW

    I love it.


    by Thelittleleslie

    This ap always helps me with my homework or when I'm curious about what a word means. Never let's me down! It's also really easy to use.

  • What the app?!?!?!

    by Glumglumbugbug

    This app is so helpful! Thank you do much for creating it!

  • Great App

    by dodatstik

    I love this app!! it's perfect!

  • Sheryl's point

    by FB frustrations

    The reason for the three stars is because once I get past the annoying functional issues, I actually get what I need. When I begin to type in the word I need defined, the page moves to another list of words. I have to wait for it to reset itself, then I can proceed with typing in my word. I loved this Ap when it first came out, but this newest version has quirks.

  • Gratitude!!!

    by Scholar1217

    My vocabulary has increased by using this resourceful app. I'm very grateful to everyone that collaborated on this project. Knowledge is power!!! Two thumbs up!!!!

  • Great app

  • Great app

    by Jroc1074

    Excellent app!!!!


    by DLHornsCXM

    This is my goto app when I need to find the spelling of a word as my spelling has never been great and nearly 30 years after graduating high school, it's not gotten much better. I'm not a 5 star kinda guy and I feel they can always get better but it is a great app. I've been using this app since my first iPhone 3, 6-7 years? I'm not one to keep apps that aren't very good, user-friendly or not used much and this is none of those.

  • Speech to text doesn't work

    by cridernickname

    Speech to text feature doesn't work. It starts listening but it never stops listening. There's no way to make it stop listening so there's no way to submit the spoken word.

  • Love word of day.

    by Adj123

    All round great for cryptic crosswords too.

    by TcMd45

  • Wonderful App.

    by Twistedfate0708

    I personally love this app. It's definitely my "go to app" for when I'm reading/writing/in-a-thinking-mood. Being on who loves English and learning new words, it only does it's job, making me feel confident with what words I use when I write/talk, etc. Also, I preferred the older version/layout of this app, but the newest upgrade is very clean n' crisp..easy to maneuver and just as easy to use! I use this app for pretty much everything and love learning new words on here; it's very helpful and I find that to be the best feature of all! Thank you(:

  • I love this app, it is so helpful.

    by GlitterLioness

    I like that the app allows you to speak the word that you want the meaning (or spelling) of. It helps when the kids want to spell correctly or just want a meaning without typing. I use the medical dictionary daily for my job, especially for rare diagnosis terms.
