Longtime User and Great Lover of App
I’m always curious. I really like this app because it just feeds my curiosity. With the exception of the other daily use apps, like Safari/Google, time clock, and calendar, this is my most used app. I love having verbal pronunciation because I’m not always right with the phonetic written pronunciation. As another reviewer stated, I really appreciate this app because before I used to keep notes on words to look up later that I had come across in writing or audio that I didn’t really know the definition of. But by the time I’d great to looking up the word on the net, I’d likely forget the provenance of the word’s usage. Most of the time I have an idiomatic or casual knowledge about the word but I like to know truly what is the definition. Along the way I’ve been very surprised to find that the definition is completely different than what I’ve thought. In fact recently I discovered that there is a word I often hear used and have used it as well but completely incorrectly.
Long time ago Dictionary integrated the Thesaurus which is excellent since I also always like to see the synonyms and antonyms of the word I’m looking up to not only solidify the definition but also to expand my vocabulary. I would recommend this app to any wordsmith like me.

Thank you! Thank you! We love positive feedback! Sometimes we all misuse a word from time to time, its only human after all. We use the app probably just as much as you do to make sure we are using words correctly 🤓
Improve use & enjoyment of language, with this perfect blend of conciseness & thoroughness
I use this app all the time, and it’s right at the top of my list of favs (surpassed perhaps only by Blue Letter Bible’s app). I have always loved words, and a mentor once gave me a sage admonition never to use a word I couldn’t define. He insisted it was arrogant. I’ve found his challenge has helped me be more precise in my thinking, humble in my attitude, and appreciative of others’ wordsmithing skills. And it makes learning from others more fun.
Well, this program just facilitates all these. In the world of language, it allows for real-time, “point of care” use and learning. I’ve looked up things while in hospital meetings (I’m a physician), while waiting in line, writing emails or other documents, and writing reviews for iPhone apps. I love the etymology tool, as it helps make definitions and nuances easier for me to remember, and the words themselves more vivid & enriching.
I suggested the app to my son recently, as I’ve found that regardless of what kind of work we do, communication that shows attention to word usage (as well as grammar) captures people’s attention — and rightly so.
If you want to improve your use, understanding and enjoyment of language, I think you’ll find this program very valuable. Strongly recommended!
audio no longer works since last update
since your last update, the audio no longer works on iphone XS Max, when trying to use pronunciation feature. i’ve been waiting for a new update to correct this feature for several weeks. i have now started looking at other apps that have this feature. up until now, i have used your app for many years without any problems that i can remember. however, this is a very important feature and used very frequently, now rendering the app useless to me fifty percent of the time. please take note.
Not so fast there “wrongpants”. Your audio is STILL NOT fixed completely... it does appear to be working on iphone when manual ringer is turned on, however, not when turned to vibrate, such as my phone has always been set to for many years. So whatever you have altered is still not being picked up by your brain trust, which means you are still unaware. These little details are big deals to phone owners who have their phones set up in specific ways. Anyway, this little irritation is so unnecessary. Why fix things when they are not broken? Why post updates when you don’t test basic features? One unnecessary improvement shouldn’t negate basic features. Good luck with all that, there are plenty of clueless app providers out there so your not alone.

In this version we changed the audio settings to respect the volume settings of your phone. For example, if the audio or ringer is off on your phone, the pronunciation button will not have audio. Try to turn on your audio and re-try the pronunciation. Thanks for writing your review!
