The app provides definitions, thesaurus, encyclopedia, medical and science definitions, rhymes, and more, and you can customizable tab order. That's all fantastic. It's useless, tho, without an internet connection unless you download the offline dictionary. But then you get definitions and thesaurus but lose everyting else, even when connected to the internet. So you get either all the features some of the time or only a few of the features all the time. And that's just stupid.

Our app does require a network connection (cell/mobile network or wifi) to function. Additionally, we do offer an optional in-app purchase of our Offline Dictionary, which gives you access to our *house* dictionary and thesaurus while offline. Due to both licensing & size, the offline dictionary does not include third-party content.

It would be nice to be able to see a picture of an example of the word, instead of having to Google it afterward. Update 11/4/22: Same annoying problem as before where you tap in the search box and the keyboard doesn't come up. Also it seems like you should be able to toggle between dictionary and thesaurus under the search box, but it doesn't work when you tap on it. 11/8/22: It takes forever to open, it's quicker to just open Google. What did we pay for?!

Happy to share that our fantastic app team worked on a new update which we anticipate will help the keyboard issue. Please do update to 9.9.3 to see an improvement in the keyboard responsiveness. Note that we did just release this today, so it may take a bit of time for you to see that update in the Play Store. Thanks for using our app!

I do have to say that this is the best dictionary app I've found. Awhile back I gave this app 3 stars because of some issues with internet connectivity, and transforming from the free version to the full version. At this point literally every problem I had with the app has been addressed and fixed! I then re-rated it 5 stars. After using the full (paid) version for quite awhile, I have to once again drop my ratting to 3 stars because of deficiencies in that alternative dictionaries. More.,.
