One of Two of the Best English Dictionaries

Get yourself the Webster Dict. app AND THIS ONE, Collins Dictionary, and you will be set. Collins has a better presentation, and allows you to browse it on split screen (Webster doesn't have that option, as of this review), which is convenient. You will not be disappointed.


Well done!

This is the most well designed app I’ve seen in iOS. Great UI and features. I just wish the same developers create an app with the same style for Collins English-French dictionary (and better other languages).


Not worth it

There are better options out there. My vocabulary is fairly good, so I use this to look up rarer words. It routinely fails or is otherwise extremely limited. Merriam-Webster is always better in my moment of need. So I’ve deleted this from that precious main home screen.
