Customer Reviews

One of my all-time favorite apps

While I have several other dictionary apps on my iPhone, this is — hands down — THE most enjoyable of them all! The featured word of the day is often one with which I'm familiar but there seem to be enough new terms to keep me interested. What really occupies my time are the featured topics with links that prove to be huge "time sinks". I find myself spending way too much of my evening chasing down details of engrossing subjects (people, events, significant dates, trivial tangents, you name it, the editors come up with all variety of fun and engaging tidbits). The matching word game towards the end of each day's entry is just challenging enough to make me think, even though I usually get a perfect 5 out of 5. So at the conclusion of each day's offering, I feel I'm "above average." It's a nice way to spend time before I turn off the light and go to sleep, with new ideas, a better vocabulary and a boost to my ego.


If you like words and their power, then this is for you. Great way to check and improve your vocabulary. Strange word when reading, just an ap away to find its definition. Nice daily games and other interesting information.
There are two small problems. One, the weather connection for Boston does not exist so no local weather is offered daily. A surprise, since Boston does have weather and several reporting places. The second is the failure of some articles to fit completely on the screen. Text disappears at the edges, and, at times, it is very hard to scroll through the article. All in all a great ap. One every person and student should have on a cell phone.


This app is my go to for any word to define,pronounce, and origin. Bookmark is high on my list. It allows me to safeguard my words. I had to replace two iPads and thought my bookmarks were lost. To my surprise they sync to both iPads and the free and paid app. Two suggestion.. The online bookmark doesn't include from both apps and iPads and vice versa. Also, wish I could look up previous words of today..this feature is only located on the online version. Other than that I'm smarter.
