Does what I want over the stock Android dictionary app, specifically look ups within look ups. The overlay on the center of the screen is obtrusive though, I'd prefer if it popped up on the lower half of my screen without a dark overlay over the rest of it. Being able to quickly look up a word and immediately re-read it in context is nice. Edit: Reachability setting doesn't change that the box covers up text underneath it. Imo, the box would take up 35% of the screen without obscuring any text.

The app is, in my mind, and absolute must have for everyone! No longer can people make an excuse to not expand their vocabulary or misuse a word. Having the ability to copy any word and get a quick definition of a word. The only suggestion i could give is i'd like additional sentences giving context to the words, but other than that this app is flawless and will always be the first app i download whenever i upgrade phones. A++

Seems like a great app. Unfortunately, though, it isn't compatible with Android 10 or up; which you don't find out until after installing it and then you get a pop-up. I really wish it was stated in the description. Waste of time. UPDATE 01/27/21: In response to Dev's comment. It does work in Android 11 by selecting/highlighting a word. But it doesn't seem to work universally in all apps.
