Great uniqe word lookup

bayoikal on

Saved me when I needed help coming up with ideas by word for my writing

Very disappointed.

OldStoneFaceVimes on

Stick with Wolfram Alpha - this app excels at nothing other than chipping away at your net worth and increasing your icon count by one.

Overpriced and not useful.

DickL13 on

The free, general app has the same information, or you could get a free dictionary app that will let you link from the results, instead of requiring a new search every time.

Was looking forward to purchasing this app.

Damon_Williams on

But can away totally disappointed. given how great the WolframAlpha app is, I decided to flip a buck for this - and I wish I had that 99 cents back. The UI is hideous, and hasn’t been updated in years. The look, feel and response all seem from am iOS two, three versions ago. It does what it purports to do fairly well, but from an outfit such as Wolfram, I just expected more. So two stars for its creation, existence and filling a niche, but three stars off for horrible implementation and UI.

Keyboard obscures screen when I type

Entropy123 on

With the Wolfram name I expected a great deal. I am disappointed. When I type in a word that needs definition, the keyboard obscures the text entry field. I can't see the words I am typing in.

Does not do synonyms

rippercat on

Asked for synonyms for "generous" - no synonyms produced.

Unnecessary and Incomplete

iByron on

Everything here can be done through the full WolframAlpha app or the WolframAlpha web site. If you've already paid for the full app, no need to shell out the additional buck for this. If you do buy it, prepare for disappointment. The words WA knows is a severely limited set. I attempted to use the Anagrams function to find anagrams of my name. It found none. The Internet Anagram Server finds almost 1400, and I could do a dozen just off the top of my head. If you happen to hit the words WA knows, the information is interesting and in-depth. I recommend the full app. though. You'll get much better value for that price.

this is garbage on the ipod, but very useful on the ipad.


Sapphire415 on

It's a useful app but it constantly crashes or freezes so I uninstalled it.

missing too many words

boorman56 on

I play scrabble and attempted to use this app. Too many times words found in scrabble dictionaries were "unknown" on this app. No good.
