Customer Reviews

So easy and helpful

Love this app. It is so user friendly and I usually end up spending more time on it then I had planned. I find what I'm looking for plus learn new words all the time. I especially like the fact that I can hear the correct pronunciation of each word, read examples of each word's usage, learn the origin of the word, and learn what year it was introduce into the English language. I've had this app for many years and will keep it for many more years to come. I use it constantly. When I have a little spare time I'll open it and just enjoy myself discovering new words or even refreshing my memory with words that I learned long ago and just forgotten.
I highly recommend this app to everyone and age is not a factor. My grandson and I would "play" with this app even before he learned to read. I'd find funny and silly words, (Cacophony! That was a big hit) I'd let him hit the speaker icon and we would laugh, be amazed, and just have fun with words.
If your on the fence, download it, try it, and if it's not what you expected, then delete it, it's that easy! I'm pretty sure you will keep it! I hope you can enjoy this app as much as I do. I love learning, and its simplicity allows me to learn all the while enjoying the process. I hope my review is helpful, if nothing else, it is an honest review. Enjoy 📚 ✍️🗣

Could be better

Definitely handy, BUT...
This app needs to blink right open. Of all my apps, this one opens the slowest. The amount of time it takes me to paste the word in and click search is the same amount of time as opening the app. It may only be 3 seconds to open, but I can use the web browser almost as fast. This app needs to be thinner & lighter. I feel like i am using a web page instead of an app. Also, it would be nice to be able to configure the main page and which content is displayed. All results should include thesaurus and dictionary results. The dictionary and thesaurus slider button should determine which results display first. I want to like this app but it seems as if it is just a wrapper for the web page and does not seem to run like an app that makes use of the phone's local resources like other apps do.

Great for writers and readers

I was considering paying upwards of 25 dollars for the Oxford English Dictionary app. While this app doesn't offer quite as an extensive look at a given words etymology, it does however, offer concise definitions at a rapid pace. I love how easily you can toggle between thesaurus and Dictionary- a tool I find invaluably useful when writing. It's easy to clear the search bar with the x to begin a new search. I find this app to be even better than the desktop webpage which I used frequently at university. Dictionary & Thesaurus
