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.

Enjoying to use and comprehensive


I love using this app. This app is not a one trick pony and does it all in a user-friendly environment.

To further improve the usability of the app, I think all sections (e.g. definitions, thesaurus, learners) which are divided by tabs can be put together on one swipeable “General” tab. In that case, you don’t have to press 12 tabs one by one for a thorough investigation of a term considering the fact that many of them are irrelevant or without entry. Tabs can remain there as anchors for faster access to a specific part of the General tab.
