Ratings and Reviews
Improve use & enjoyment of language, with this perfect blend of conciseness & thoroughness
I use this app all the time, and it’s right at the top of my list of favs (surpassed perhaps only by Blue Letter Bible’s app). I have always loved words, and a mentor once gave me a sage admonition never to use a word I couldn’t define. He insisted it was arrogant. I’ve found his challenge has helped me be more precise in my thinking, humble in my attitude, and appreciative of others’ wordsmithing skills. And it makes learning from others more fun.
Well, this program just facilitates all these. In the world of language, it allows for real-time, “point of care” use and learning. I’ve looked up things while in hospital meetings (I’m a physician), while waiting in line, writing emails or other documents, and writing reviews for iPhone apps. I love the etymology tool, as it helps make definitions and nuances easier for me to remember, and the words themselves more vivid & enriching.
I suggested the app to my son recently, as I’ve found that regardless of what kind of work we do, communication that shows attention to word usage (as well as grammar) captures people’s attention — and rightly so.
If you want to improve your use, understanding and enjoyment of language, I think you’ll find this program very valuable. Strongly recommended!
Really helpful app
I have to look up words I see or read that I’m not familiar with. It drives me crazy to not know what something means. I have a long list of words to look up and learn which at the time I heard them, I didn’t have time to stop and look up.
I like that I can have the words in question voiced to me also. That’s a big help. And it keeps me from embarrassing myself by pronouncing words incorrectly. I rarely pay for a lot of apps that charge you to get rid of the ad’s, but this one was worth it. It’s very easy to navigate when you’re in the app. I just love having a Dictionary in hand whenever I need one. There isn’t a downside to having this.
Should stick to definitions not opinion
I have really enjoyed this app for the most part. I share the word of the day with a friend almost every morning and we really like it. She is an avid crossword player.
What I find unacceptable is that the extra articles tend to lean on the trendy politically correct or just downright liberal end of the spectrum. Since I'm not one of the millennials it seems to target, I actually know a bit of historical context for many of these articles and it's not as they portray them. It's not "balanced" or objective. I would like to see these little tidbits of interest be just informative not simply opinionated, trendy and vapid. If your going to include these at all do a better job. Or maybe include one of those disclaimers that says this is just an opinion.
