  • Love it!

    By Madulting
    Easy to use and perfect for a quick lookup! Also, great to be able to favorite words... I love to favorite every word I look up and then randomly go back through them! The word of the day is also convenient, & they pick great words! I’m incredibly happy with it!
  • Smooth, Fun, Informative

    I use this for school all the time. I LOVE the “Word of the Day” feature. The app itself is smooth and reliable. I recommend it to all my schoolmates for easy searches.
  • Use all the time

    By Deb-jinxy
    Love app. Use all the time. Save words I use quite a bit.

    By Zellojello
    Terrible app. Kept taking me to the App Store randomly and went to random apps for example; Big Fish Casino. Upset that an old school dictionary company would have this take on advertising.
  • Love This App

    By MsMagilacutty
    I use this app on a daily basis. I love the daily word feature. It gives the definition along with the history of the word and I appreciate that you can tap the word to hear it pronounced correctly. I look forward to the Games feature as it updates each week. I learn a lot by using this feature of the app. And it is free!
  • Awesome App to learn vocabulary

    By Soft Tan
    I use this app to learn vocabulary for my GRE. It’s very convenient! I love it!
  • App suddenly crashes when swiping back to previous word

    By lekywizzle
    Dictionary app just freezes and crashes when swiping back to previous word via which you checked the synonymous words. For example when I check the word sabbatical and clicks On the synonymous beneath(leave) it takes me to leave and when I try to swipe back to go back it freezes and crash. Please fix this. Lovely dico app anyways.
  • Useful and convenient

    By Hawaii listener
    I use the app all the time when I write. I would use my real-world dictionary but it is a little yucky (it’s so old) and this app also has a convenient thesaurus.
  • Pronunciations

    By Disscrabbled
    There is a problem with word pronunciations; they cannot be heard, even when volume is high. Had same problem last year and finally it was corrected.
  • Fave dictionary app

    By DDrobloxHUMAN
    I use this app almost every day, if I don’t know the meaning of a word, I get on my iPad then look up the word then I get back to writing knowing what the word means. Translated: ONE OF THE BEST APPS EVER!!!
