Ninjawords Dictionary is built upon three ninja facts: they are smart, fast, and deadly accurate. Three other things this app boasts are freshness, high quality, and ease of use. Words all stay on the same page while looking them up, avoiding flipping back and forth through page after page. Other features include recents, favorites, a thesaurus, and pronunciations.

App Store Description

"The best electronic dictionary I've ever used." -

Ninjawords is the simple, fast and deadly dictionary for the iPhone.

Ninjas are three things:
1. They're smart
2. They're quick
3. They're deadly accurate

Ninjawords was built on these principles. We made it because we saw that the low-cost dictionaries on the App Store are slow, cluttered, and all use the same bad data source for their definitions.

Ninjawords takes a different approach. We use awesome, fresh, high quality data with more words and synonyms than you can throw a ninja star at. And best of all, when you look up your words, they all stay on the page. No need to flip back and forth between different pages as you look up multiple words.

* Works OFFLINE.
* Spellcheck!
* Word of the day each time you start the app.
* Touch to get a random vocabulary word.
* Recents.
* Favorites.
* Thesaurus (each definition has synonyms).
* Pronunciations (tap to play)
* Fast like a ninja.

"Exactly what I've always wanted in an iPhone dictionary, and, yes, with both a better user experience and better dictionary content than the other low-cost dictionaries in the App Store."
John Gruber,

"I've been using the dictionary since the day it was released, and have since deleted all other dictionaries from my iPhone. It’s good. It’s really good."
Milind Alvares,

"A simple, lightweight, well-designed dictionary application."

"It leaves the competition in the dust. It is a ninja-based dictionary, after all."
