On android, you have Livio which is offline, tracker free and free of charge as well.

That's pretty disappointing that MacOS has an unmatched dictionnary app but iOS is forgotten while there is decent options on Android.

Not a standalone app, but on iOS you can highlight any word and select "Look up..." to get a definition. I use it frequently while reading the New York Times.

I believe it works offline, too, since the device I use for the Times is almost never hooked up to the internet.
