  • Come on

    By raemitch2016
    This may be a good app but I gave it a one star as I felt it was a come on. I paid $19.00 and perhaps a little more as the original app had lots of ad so because I do not like the ads I paid to remove them and then you need WiFi to look at the app and I do not have WiFi on my iPad unless I hook it up thru my phone. Such a waste of money. Apple needs to do better when it comes to the app you have to guess at the price. Apple used to give you the price now they say guess at how much it will cost you. I am sure there are lots of free app for a dictionary sorry I got rip off with paying twenty bucks for an app I cannot use.

  • A Great Disappointment

    By Myra Murk
    This once-excellent app has proved itself to be a great disappointment. When I transferred from my previous iPhone6 to my current iPhone. an iPhone7, I lost aural pronunciations, which should have been grandfathered in.
  • Continuously crashes on startup

    By billmcfa
    It used to work, now won’t start at all. Update: still broken
  • Complete & accurate

    By Laura_CS
    NO ANTONYMS. A Thesaurus, by definition, includes both synonyms and antonyms. Despite the protest by the “support” staff to me that their description states they provide synonyms, in standard English, such a statement does not preclude the inclusion of antonyms, particularly when the service is termed Thesaurus, which is clearly defined and widely understood to have a specific meaning. We do not yet live in the nonsense world that Donald Trump is trying to create, therefore: This app is falsely-advertised, and thus, the “Premium” fees are being charged illegally, i.e. for a service that is not provided.

  • Kill the splash screen

    Its an unnecessary delay to find the word you need. We have no reason to look at the cover for 5 seconds everytime!
