Ratings and Reviews
Where did all these forced ads come from???
1) The ads are overkill to say the least. This used to be. 5 star app- I never had to deal with all these stupid pop-ups and inescapable video ads. You’re lucky Siri’s integrated thesaurus is so limited or else I would’ve deleted this app a long time ago.
2)Personally this has become a more recently growing issue. I’ll search thesaurus for word, “x”, with 0 results, no synonyms available. However, if I search for something synonymous with “x”, such as “n”, a whole list of synonyms pop up, including “x”!! ugh 🤷🏻♀️🤦🏻♀️
Other times when I’m looking through a given list of synonyms , I’ve clicked on a word for its definition, but there is no definition available bc the dictionary doesn't even recognize this word exists. . Vise versa after looking up a definition , I’ll try to use thesaurus on it , but it comes up no synonyms available.
And trust me both problems are equally frustrating. Seriously, how can you know the synonymy of a word on one side of your app, but can’t deliver its friggin definition on the other side. Stupid.
A wonderful tool for elementary students too.
My daughter uses this app almost everyday as a companion to reading her novels. She oftentimes comes across words she is unfamiliar with. The dictionary app provides a quick way to access words while she still holds onto her book. We also did homework together last night and the thesaurus feature was wonderfully designed so that one can search antonyms and synonyms while effortlessly switching back to the definition of the original words and newly found words. Lastly, this is a "must purchase" app. You'll experience the app best by having no interruptions. This is important especially if you want a child to use it to build vocabulary while reading independently.
I love it and am grateful for it.
The interface is enjoyable. I appreciate the simple themed blog posts about words. I like how you can favorite words and the easy switch to thesaurus mode. It would be cool to have fewer ads, or at least a different type of ad. Those upper corner countdown ads are irritating. As a songwriter I’m always playing with words, and not just rhyming, but syllable breakdown - lining them up with different melodic lines and rhythmic ideas. It would would be cool to markup the words within favorites - have metadata. Like be able to write “about” the words, sort and group them almost by project, and have them linked to audio and journals docs in like a google doc or another app. Thanks!
