    Much more than I expected
  • Great dictionary

    By Ovid1037
    No complaints. This dictionary works as I desire.
  • Good App. Incessant and annoying prompts to rate.

    By jawalsh
    Excellent dictionary. Pretty nice app. Positive feelings about the app, however, are destroyed by the annoying prompts to rate the app. It seems every time I open it, I'm forced to click through a prompt to review the app. I'm working and want a definition. I don't want to be slowed down by intrusive prompts. I've finally given in and am reviewing in the hopes that the prompts will go away.

  • Bring back the old tools

    By Dk Danes
    Missing letters fillers, and word unscrambler please. This was in the old AHD apps. Also, keep the setting when Thesaurus is set as default tool. Right now it always revert to dictionary. Provide option to open search upon opening app. Add letter index to easily navigate word entries in the list.
