User reviews

Excellent tool!

Thank you very much!

Incomplete

I generally like the app’s functionality with some niggles. However the biggest issue is the absence of some relatively common words eg acuity.
Also the linking seems faulty eg if a search for ‘recant’ gives a list including ‘disavow’ then shouldn’t it also be vice versa? Real shame.

Favourite

Buy to support a developer who doesn’t collect any data and offers their product for free as well. Nice QOL additions for the price.

Small annoyances

I have been using this Thesaurus App for many years with mixed success, more and more recently a word that I enter is not recognised. I check the spelling so I know that is not the issue. I enter the same word into its sister dictionary and it comes up . It is not as though the words are obscure, the latest was crustacean, not an obscure one I would have thought. I don’t know what the developers can do other than increase the stored words. But I suspect that is easier said than done. I will just keep my fingers crossed. Apart from that an excellent App.

The faulty interface irks

The search field is not immediately available unless triggered. It opens to a random entry and searching requires a few unnecessary clicks.
