Customer Reviews

Individual Letters Crash the App

One of the better dictionary apps with some really nice features. I especially like the ability to use it as a spell-checker, which I use it most often for. But once and awhile, I look up a known word and it is missing.

The main problem, however, is that if you search for a letter that is not considered a word (like x, y, or z), it crashes the app. Happens every time.

Best Dictionary for the iPhone

I have tried almost every Dictionary for the iPhone and this is by FAR the best. The bookmarking system is top notch, the auto-guess system for when you misspell a word is great and it even has a thesaurus with hyperlink capabilities so you can immediately jump to any word. Bottom line: buy this app.

Needs update

This apps' functions are great but it needs support for the retina display, the ability to customize the toolbar like you can do in the iPod and Remote apps, and needs the spell check/suggestions to appear and update while your entering a word. This last change would make the app much faster to use.
