Really useful app. I have only one, but serious complaint: the reference hyperlinks in the results are large and very sensitive, and more often than a care for, while I am trying to scroll down, I touch a link which takes me to another result - another word. I use a Samsung Galaxy S22+. Not sure how, but please address.

There are many, many words that are not found in the app that you can find in the online dictionary. So when I need to look up an unusual word I need to double-check its existence. Maybe at least list the word and have its definition unavailable while offline if size is your concern, but a dictionary with missing words is a failure.

I can't get the audio pronunciation to work no matter how much I fiddle around in Settings. Also, this app has a weird pausing after you start entering in a new entry, which causes you to reenter the word a second time. I can not recommend this dictionary app to anyone.
