Really helpful app

i dare you to show this

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.

Organize Favorites?


So far I really like this app! But to take this to the next level I recommend having a way to organize favorites somehow. When learning vocabulary it has been proven that we learn more effectively by organizing words by ‘meaning’. Why not allow users to custom make a folder or place holder? Additionally syncing to iCloud in this respect would be ideal. Developers please take note and consider this tweak for your paid supporters. Would be worth 10 stars if they could add this feature... I hope I don’t get asked again during my session(s) to rate your app, especially since I denied notifications at the root level.
