Customer Reviews

This is really one of the best ones I've seen!

Even though this is my favorite dictionary app, THUS FAR, it has been kind of annoying when I tap on "Examples" or "Synonyms", and there will be no information. So, I end up Googling the word to find out how it is used or more about its meaning. Like today's "Word of the Day" was SUPER VAGUE & had NO information when I tapped on "Examples". It truly needs improvement.

It even offers "off-the-cuff", slang words, and if you have made some in-app purchase some, it will give you examples, synonyms, it just goes on. Honestly, no matter what phone I ever have, I plan on always purchasing this app and all of its features. I L🍓VE the "Weekly Quizzes", vocabulary has always been part of my passion for writing. Please keep up the great work. I even try, each day, to use whatever the last "word of the day" that was sent to me, whenever I think f it until I get the next one.

Along with the weekly "Word of the day Quzzes", I thought you might want to really challenge us a little more by possibly having trivial quizzes on daily words, like the origin, etc.

Also, it's kinda easy to do like one little word quiz per week, but I would suggest some sort of small incentive to make kinda really do our homework, or maybe you could find a way to see if we'd practiced any words or phrases that we personally don't normally use. I don't know. Just a thought.

Incredible tool

I've been writing and teaching writing for more than 50 years and regret that this powerhouse was not available sooner. This is not just a dictionary, it's a plunge into the heart of the language. I was delighted when it was just a dictionary but the add-ons make it much more useful. I seldom use the add-ons, but when I do, I find them incredibly useful. I am anxious to support these developers in their work. These latest improvements make it even more intuitive. I can get lost in the app like others playing Halo. Thanks for keeping the language fascinating and inviting.

Love It!!!

I really like having a dictionary close at hand, ready to whip it out of my pocket to discover a new word or confirm a pronunciation. I would have been willing to pay for it (maybe I did - it's been a long time since I got it). If you enjoy knowing what words mean, then this is the app for you. Occasionally, I hit the commercial lurking at the bottom of the screen, but it's very easy to find the little "x" to get rid of it. Lots of good stuff about this one - lots to like.
