Customer Reviews

Excellent, superb, and exceptional

This app is excellent, superb, and exceptional. Now, you may wonder why this may be, but, I assure you there is no need for wonder, because I am about to tell you why this app is excellent, superb, and exceptional. This app is very easy to use; it is also very quick, and if you do not know how to spell a word you can use the voice feature. The user friendliness, the quickness, and helpful features make this app, in my opinion, excellent. This app is also a thesaurus, an encyclopedia, a medical dictionary, and offers advice on grammar, slangs, and idioms--this, in my opinion, is sufficient enough to consider this app superb. But, wait, there is more. This app also gives you a word of the day and even allows you to save your favorite words with the favorite word feature, and it also provides you with fun, interesting facts presented in quirky slideshow--certainly,with out a doubt, this is enough to consider this app exceptional. You see, this app is excellent, superb, and exceptional, but you will not truly see this unless you get the app; trust me, you will not regret downloading this app.

This app is brilliant!!

First of all, this is the best dictionary I've ever used. It's way easier to use and more resourceful than a book, and more convenient than a computer. It's nice being able to just pull out your phone and look up a word at any given moment. The features of this app work fantastically and covers everything you would need to know about a word, including: the definition, pronunciation, part of speech, examples of use, origin, and even has an equally great thesaurus so you can find a word's synonyms and antonyms.

This app should be a must-have for everyone with an iPod/iPhone. It's great for writers, enhancing your vocabulary, and even making up new words and usernames. I couldn't recommend this app any more.

⭐️⭐️⭐️⭐️⭐️ all the way!

Hours spent on this app, absolute favorite

This app has sparked a desire in me to learn all the wonderful words in the English language. Some of the newest features such as the learners section are an amazing addition. Additionally I am happy that when going back to my favorites list from a current favorite, I don't end up at the top of the list like it used to. This is useful as I have 400+ words making sifting through them tedious. I like their flash card app A LOT but would be even happier if they integrated a flash card option for this app, so I could quiz myself on my favorite words. PLEASE PLEASE make this an option and I will love you all forever! Cheers to expanding your vocabulary with this amazing app!!! Dictionary & Thesaurus
