  • 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.

  • 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.

  • Fantastic new design

    By Nickonthehill
    This is the best dictionary - fast, efficient, uncluttered, all the features you need for a quick look up and nothing more to distract your attention. Really good job!
  • ‘Bubble’ is also a noun

    By Viiv
    Within minutes of buying this app I encounter a glitch. The thesaurus gives no synonyms for the noun version of ‘bubble.’ A quick web search reveals: Bubble (noun) synonyms: Ball, blot, globule, driblet, droplet, balloon, barm ... etc Maybe worry about new words like ‘hangry’ after you’ve fully exhausted the basic English language.
  • A Treasure Trove Of Knowledge!!!

    By Heckla n Koch
    After trying out most app dictionaries, I strongly concur that all other developers should strive to follow this exceptional blueprint of Merriam Webster’s!!! I bought the paid app without much ado. Nothing compares to the word games and the inbuilt thesaurus!!! The ‘word of the day’ is always refreshing!!! Don’t hesitate, download the paid app, it’s a treasure trove of knowledge!!!
