Customer Reviews

Fabulous: more philology!

This is a stupendous app, especially free: it's easy to ignore the adverts, so I use it daily, & place it next to my reading subscriptions so I can quickly reference exactly what a writer wants me to know. I love that it includes the origin & etymology of the words, however basic it is: more depth here please!
The Daily Word can be mildly annoying, but is easy to opt out of. Additionally, it is irritating that it doesn't recognise it's own hyperlinked words (eg in the origin section) written in capitals; instead, it gives you a list of words it "could" be, ie the exact word you're looking for, simply written in lower case! But as its therefore just one more click away, worse things happen at sea. I also wish it predicted misspelled queried words better.
However, while saying that, this is the only app review I have ever bothered writing / rating, I am that impressed! Download, no need to buy, & use!

Excellent app, but…

I think this app is fantastic, I use it daily for all my etymological queries but I have one small gripe…
I fully upgraded the app with all the add-ons though I did so individually rather than via the 'premium bundle', as such, I'm plagued with popups, trying to compel me to upgrade to remove the ads.
Obviously I'm reluctant to fork out on this without any additional content being granted. Thus, I am frustrated by what is, in all other respects, an excellent staple app.

Fun with words

This is a very useful dictionary and thesaurus, not just for crossword addicts. Clear and easy to use. But what I really enjoy is the Word of the Day. It pops up on the screen each morning and it's irresistible to find out the meanings. Amusing and educational too. Dictionary & Thesaurus
