A great and important work demeaned


The OED is the benchmark by which all other English dictionaries are judged. It is the ultimate arbiter of usage, pronunciation, and etymology of our language.

I use it daily in some form, whether print or digital. It is a vital tool for many writers.

So, why only a three-star rating? Simply, because the company tasked with producing the digital version of the essential and estimable work has included an extremely annoying, self-indulgent, feature: the app periodically requests a five-star rating via a cheesy, simpering pop-up. There is no provision to cancel future pop-up recurrences without landing on the app's App Store rating and feedback pages and entering a rating. Hence mine.

It's true that if you do click the pop-up, you are actually free to rate the app as you desire. And the work in its own merit is unquestionably worthy of five stars.

Nonetheless, the experience of being repeatedly begged for adulation is enough of displeasure that I am impelled to downgrade my rating, at least for now: The feature is unworthy of the OED and should be forthwith removed.

A previously user friendly app turned into an annoying experience


Unfortunately this app falls short of the the highly usable original Deluxe edition of OUP's dictionary and thesaurus. The original version would allow tapping and then transferring to the relevant definition for words within the text of the definition, thus facilitating endless cross-referencing. What a great tool it was! Alas, not any more.

Beware of the app's (Mobisystems) demand, every so often at opening, to demand a 5 star rating. Rather audacious and unprofessional.



My main use is to look up British and otherwise obscure words and phrases that don't appear in other dictionaries. The app overall is quite useful, but I have two complaints: 1) it always starts in "thesaurus mode" and there seems to be no way to default to dictionary lookup, and 2) it continually pesters the user for a five-star rating. (How needy, and how unprofessional.)
