Reviews
Five-star reviews of this app on Google Play.
I rated it five stars because this dictionary is amongst the best dictionaries I had ever used. When you look up a word,it gives you multiple definitions in different perspective. It's also displays the word in its nouns, adjectival, adverbial etc and the overall part of it is that,it's very simple to use. I really appreciate this app and I can recommend it any English speaker who hasn't tried it before.
Like all the other Dictamp apps that I love so much, this too also has all the same amazing features. I love that I can add my notes to entries, such as quotes from newspapers, magazines, etc, practice vocabulary and also add my own entries, thus creating the perfect dictionary. What's really amazing is that all my notes and entries are stored safely in Dropbox, that means I don't ever have to worry about losing any of them. Learning a new language has never been easier. Thank you guys!
Being wildly enthusiastic about their Polish-English dictionary I looked at this dictionary out of curiousity. It too is very good, with a clear explanation of the meaning of the word, together with examples of its use in idioms and phrasal words. The word, get, is over-used in English and can be confusing to learners of English, but in this dictionary if you search for get, you get so many examples of usage that it helps to make a particular usage very clear.
An excellent data-saving dictionary with tons of customization options and bonus features, AND unobtrusive ads. My favorite feature is the hilariously cursed version of Wordle ("Curdle") that I play daily. It holds nothing back; any 5-letter word can be valid no matter how technical, obscure, or obsolete. A great, silly challenge with answers like ALEAK, TWERK, NGUNI, and my favorite, SLEEV (defined as "nonstandard, simplified spelling of sleeve" AKA "sleeve but spelled wrong"). Never change!
The app is just amazing! Man, that's crazy. I've read a few comments here, saying that everything they were looking for in a dictionary is there in this application, but, actually, at least for me, even what I wasn't looking for is also there! It does have a lot of good features. I use it for a long time (over two years) and still simply love it a lot!
What a perfect ways to study English language, your the best I like you, upon five apps that I have that do the same thing you're the best, congratulations for the good job, my best wishes, see you again when you make repose updates, thanks.
