It would be nice to have Whitaker’s words for iphone, exactly like the one on android. There does exist an iphone Words, but it requires internet access.
For Linux users, the android Whitaker’s words looks exactly like the version running in a Linux X terminal. And it works even when disconnected from the internet.
I still find Words useful for parsing new words, and for a quick definition. When I need drill on the Latin forms, I guess a form and type it in on Words for instant feedback
