  • Great in both games and reference!

    By USN Retired
    Stimulating and provides great information.
  • Indisputable

    By LowlyWiser
    One of the most useful apps. Definitions are clearly written, and there are no typos I have also used the Unabridged, but for full histories there’s nothing like the OED. I can rely on the MW online for quick reliable answers, and it has helped settle more than a few arguments.
  • Best dictionary! You could ever have. Have been using it for several years.

  • Best Resource for Executives

    By HookedOnSuccess
    This app is a continual resource for me during my day! Many communiques produced each day contain words that serve as descriptors to lead our teams. Purchased the full app and use it extensively and continuously. Highly recommend this app to anyone, particularly writers of content and correspondence.
  • Singularity

    By Ckntz
    Really like it when word of the day summarizes the events of the past day. In a single word. Sometimes I search for a connection but usually I can find it. Frequently I use it to introduce myself to the day on Facebook or Twitter. Your word of the day is a treasure.
  • Excellent Resource

  • Accentuated knowledge

    By boxhuntersix
    I have a 1902 Webster’s and a 1964 Webster’s. I find both extremely satisfying yet, when on the go, this app becomes my tool of choice. All three have uses but this app is absolutely a necessity for writers with a busy life.
