Safety starts with understanding how developers collect and share your data. Data privacy and security practices may vary based on your use, region, and age. The developer provided this information and may update it over time.
Having fun with the word games & articles of the day, plus achievements, but missing links & broken images in click-through Wikipedia entries should be fixed. One article of the day led to an article that didn't answer the question on the main page. And no English entry for "COVID-19" makes me wonder what other major terms are missing from a comprehensive dictionary...? (Also...not updated since December '25? Hmm. 😕 )

Fair price to go Pro instead of requiring a subscription, so I did it immediately. Great grammar quizzes which I did well on "out of the gate." It was enjoyable, plus I learned a thing or two which at my age, or any age, is great. I also took the opportunity to download a couple other dictionaries from this developer. Recommend it. Please keep it updated because it would be a great loss to not have this, and not just for me.

Works well with single words. I've used English, Italian, and Spanish. Almost always gives excellent definitions. Translations are also excellent. Has alternative forms of most words and some idiomatic expressions. Occasionally, can't find a word, though. Offline dictionaries are almost as good as online, but take a lot of space.
