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 📚 ✍️🗣


I'm rating 5 stars because this is, by far, the best dictionary app I have ever used. I purchased the "example sentences" and "grammar tips" upgrades after a few minutes of usage ($1.99 each), and while I do not recommend the grammar upgrade (9/10 times there are no grammar tips so it ends up being a waste of money- I almost had to rate 4 stars because of this) the "example sentences" is a necessity if you're serious about incorporating new words into your vocabulary. The other upgrades look promising, but for now I'm chilling on the essentials. The dictionary comes with a free thesaurus and also provides the "origins" of the word you are learning which really helps me understand what kind of "emotion" the word conveys in language (it also helps create a conscious grasp on the appropriate incorporation of a new word into a sentence). The "favourite" button, however, was the ultimate selling point for me- I am now able to save my own index of new words onto my phone- portable and quick to access! This is a overall a fantastic app and I believe everyone should own at least the free version.
*one final note, they also include "words" of the day and a series of educational blogs- that's lit.

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.
