So far, so good, excellent reference material with cross-references that make it a good tool in my toolbox 🧰 The option for READ OUT LOUD on the word (not Definitions) is a precious thing for everyone. Yes, it's a lot to think of, but I'm grateful for the option 🙏 We can get into economics versus economics, but I won't go there.

Not bad but really wish this app had photos in it...that would be awesome to see photos of some of the items in the dictionary. It's a bit plain and old interface but has lots of links though so that's good.

This App doesn't have all the planets in our solar system, the planet mercury isn't included in this App, which is stupid because all the other planets are. The Developers need to work on the content of this App, because it's severely lacking information. Plus this app would be 10 times better if it included images. I'm thoroughly disappointed with this App, so I'm un-installing it! This App is a complete waste of time, I do not recommend this App to anyone!!!

I'm sorry you're having trouble. It looks like we do have an entry for the planet Mercury; you should see it on the page for Mercury below the "Mercury (chemistry)" entry. And this app does include thousands of images. Their availability simply varies from word to word depending on the source material.
