English/Spanish edition: great app; use it all the time and it rarely fails me. The only suggestion I would make is that I would love to be able to look up phrases as well. Strangely, my husband's newer version does do this but his one doesn't show the various uses of the word you look up, which mine does! Given that, I actually prefer my version but it would be great to have both. : )

I ordered Ultra lingua Spanish, but received Esperanto. I got the correct app in 3 days, but didn't get new secret password with it. It expired after 2 weeks and Ultralingua will not answer emails so I can't use it. The translation feature never worked because it said I didn't have a secure connection. A waste of money. I've found better free websites that do a better job.

Better than the newer, flashier dictionary apps (hear that, MobiSystems?). The interface is simple yet highly functional, and searches take advantage of basic computing technology, i.e. they lead you not only to headwords but also to phrases and idioms containing your search term (hear that, MobiSystems?). Excellent!
