    Simply the best dictionary.
  • Never leave home without it!

    Download this app on all my devices. Use it daily and it has saved me embarrassment many times!
  • No problem for years

    By Jackfetch
    I’ve had, and used this app for a very long time with no issues, and it appears to me that the majority of issues others have is “user error/misunderstanding”.
  • Consistently improving

    By ClosetPole
    I upgraded from the free app because I did not want advertising. I love using any dictionary while reading or in conversation or arguments, even at parties. This app is improving all the time in the direction of their bound book. I like details and etymology! The games have improved as well! ...and the word of the day thingamajig.
  • Use Daily

  • Essential app but somewhat lacking

    By alv443
    I use this app constantly. I love that you can hear a word’s correct pronunciation, that you can see words you looked up recently, and all of its other features. To the developers, however, I’d like to suggest 2 functions I often wish it had: 1) a “BACK” arrow to go back to the list or word you were previously looking at (instead of having only the main menu to work with), and 2) a way to BROWSE the dictionary like you can with a physical one — without having to use the search feature. Thanks!
