This really is so much more than a dictionary but I'm limiting my review because there isn't enough space to review all the other features. The dictionary features are unmatched. Not only does it give multiple suggestions as you type, it gives them in multiple languages. Words are split with phonetic help and results from 3 different sources are given. Etymology is given. There's a thesaurus. Then usage examples from literature! A bonus for me is that it lists Spanish verb endings. It's the best

Great dictionary, no doubt, probably the best. I was about to criticize the size of the words written in phonetic alphabet and the table used to pronounce the words. To give just one example, take a look at the word "advantage" written "ād-vân'tîj" . It's impossible to determine which accent is being used on the letter I due to the small font size used but if you're a registered user, you can actually increase the size of the font. They really thought about every detail.

I've only had it for a few days now... For some reason you App developers or to whom this goes to,are under the false assumption that we can rate an app that I haven't even had a week with... Lucky for you!!!LOL... I like it very much so far and even paid for the no ad upgrade... Compared to other Dictionary apps I've had,I was surprised by the amount of freedom this app gives so far.. I'll report back in a few weeks....😁👍🙏....
