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.)

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.

Essential app

I probably use this once a day at least. I've long loved how comprehensive the OED is. The etymologies are unparalleled and so informative. This app is mostly very easy to use and navigate. Would be nice if I could easily toggle between definitions and thesaurus since that seems like a wasted opportunity for a combined app, but that's a small complaint for all the use I get out of it. I have a few dictionary apps, but this is the one I always reach for first (usually last).
