Great Dictionary, Subpar App Layout

iLux Lucis

The Webster New World Dictionary is outstanding. However, for $15 you get this app with paltry navigation functionality. The previous dictionary edition app was by a different company (no longer supported in IOS 11), and it at least allowed you to go from a word entry back to the search screen by pressing the back button. The current app offers no such navigation capability.
It would also be nice to swipe back and forth between alphabetical entries, and also to see short descriptions attached to words in the search screen.
It would be even better to be able to see multiple consecutive entries on a single screen by scrolling up and down, without having to restart the search screen and looking up the next word, all over again.

Without such navigation capabilities this app is seriously handicapped, and you have to wonder what exactly you paid so much money for.

Developer Response

Hello, we are sorry that you have problems with the dictionary. We have released a new version that supports iOS 11, but it is still in review by Apple. It should be approved and available on the App Store shortly. Please excuse any inconveniences caused, we appreciate your patience.

Essential for news writers

It's cheaper than a hard copy and updates periodically, allowing us to stay on top of the evolving definitions that guide America's newsrooms, and have easy access at all times.

Still the best dictionary out there!


At age 60 this is still my 'go-to' dictionary! I love the ease, their updates every year, and carry it with me everywhere I go!
