  • Flashcards

    Insanely powerful / customizable system, making it extremely easy to add new flashcards from dictionary entries or import pre-made vocabulary lists.

    Look up words in a document simply by tapping on them; currently supports text files and web pages, EPUB / PDF / DOC support coming soon on iOS.

  • Incredibly Fast

    We use a custom-built database engine so fast that it can search and process results from a dozen different dictionaries before you've finished lifting your finger off the screen.

  • Well-Supported

    We've been in business for over a decade, and we offer free upgrades and free platform transfers whenever possible; we have users who bought the Pocket Oxford Chinese Dictionary from us for Palm Pilot in 2001 and are still able to use that same purchase on their brand-new iPhone 5 or Samsung Galaxy in 2013 without ever having had to pay an upgrade fee.
