Customer Reviews

'Online only' complaints

I have only just downloaded this based on many useful reviews, but I don't understand why the complaint about the amount of data that's only available online. I read it as being the dictionary/thesaurus lookup that's available offline. If this turns out not to be true, I'll be seriously p*****d off, but do you want your tablet memory filled with translations, examples, and all the other things you expect to be available online? Bearing in mind the sheer quantity of data you would view once or not at all. And come on...a wired internet connection only is a pretty rare setup hit someone using a tablet at home.

Get some perspective and enough with the spurious reviews. In that spirit, this review will be replaced by something more relevant to my experience of the app. For now, I give a neutral 4* until I have tried the paid content - the free content was excellent and the developer deserves financial remuneration.

Almost perfect.

This app represent such great value you will never regret buying it so do yourself a favour and get it now. My only complaint is that there is no dark theme option and the built in negative colour tool that appears in the accessibility section of the iPad settings is of limited use as it makes everything negative including pictures and is a bit of a pain to activate and deactivate, especially if you have already assigned a function to the triple click available for the Accessibility tools. A permanent dark theme would solve this problem and be kinder to tired eyes.

A handy tool for writing

One of the ways I revise my creative writing pieces is to look up words and their synonyms to see which ones fit the structure and style of my poems. When I saw this app, I thought it would do the trick. And I've not been disappointed.
This is my favourite tool for revision. I have bought the full, ads-free version and I would recommend it to all writers (and learners) of English! Premium Dictionary & Thesaurus for iPad
