The best dictionary app I have used to date

This is the best Dictionary, Thesaurus and vocabulary apps I have used to date. Have had a few minor crashing issues in the past but, nothing the last few months. This app is great I wish it could integrated into mail and some other apps. The word of the day is prodigious asset. For years I have had a extensive unabridged hard cover $600 dictionary on a pedestal in my sunroom I use to highlight a different word each day. With this app I now get two. Keep making improvements worth every cent of $10, you get all the information of an unabridged dictionary and copious amount of additional information. And before anyone makes a crass comment about highlighting a fine dictionary I use a special archival highlighter. It is meant to be used not collect dust. Just like this app. Use it to appreciate it.

Most useful & effective dictionary

I appreciate the efficient, well-written and real-world, current definitions with satisfactory descriptions, while still including older definitions, the helpful pronunciation audio, and the word's origins (discipline, culture), function and evolving meaning and usage, since the meaning and usage of many words are not narrow or static. Some entries include a meaningful explanation on differentiating the entry word from similar or neighboring words where common mistakes are made, providing better boundaries between (or among) such words. Most dictionaries still rely on old, rigid definitions with limited examples, failing to stay updated on a word's usage.

Good but could be better

The app (Premium) is good, one of the better dictionary apps out there. The audible pronunciation is really a plus and unlike some other apps, it is itself -audible- and not muffled.

The biggest downfall in my view, is that it doesn't let you sync your search history from one device to another through iCloud or some similar functionality; nor does it even let you print your search history to then try and combine under one list.

One of the nicest parts of having a record of ones word-lookups, is the ability to then scroll back through and test yourself and review them all, to actually learn the word vs. just having it be an in-the-moment explanation.

While the app keeps a list of "recent searches" on a per-device basis, combining them through some form of account sync would be better, since many folks use multiple devices these days.

I've suggested it to "them" a number of times through the "contact us", but have not received any response (which is also disappointing customer-service in a paid application, although not uncommon). Premium Dictionary & Thesaurus for iPad
