Customer Reviews

A fine wine that has gotten better with age.

I have been a dictionary user since release, and this is one app that has gotten better with age. While it would be nice if they put out specials where you can buy all of its (very useful) DLC into one affordable package, it still is worth every penny. Even if you didn't purchase any DLC, you are getting a robust app that outstrips other dictionary apps. And what I like about the DLC is that you just buy what you need. But each DLC makes very significant and positive additions to the app, so it is, at least, worth looking in to.

To sum up:
A great app that keeps getting better. You don't have to buy any DLC for this to be a great app, but the DLC is worthwhile as well. Enjoy.

Favorite dictionary app

I've tried a few dictionary apps, and this is the best I've found. For someone who likes to look up words independent of working on a note, it's convenient to have a standalone app, and the dictionary is larger than the others I've tried. The GUI and stability issues of past versions seem to have been resolved now with a more native interface. My one complaint is that one needs a network connection to view etymologies, but that's usually not an issue. Overall, this is the dictionary to have.

My Necessary App

I am always looking up something. Probably because I am usually writing something. This is the best dictionary app for me. Easy to use: I like the history of lookups. On my iPad I get hooked reading the articles. Upgrades aren't expensive if you only need 1-2, but this app does accrue a pretty penny when you use it as extensively as I do, rather than googling constantly. I recommend it.
