"Ultralingua has been an invaluable tool for me! I travel outside of the United States with some regularity. Ultralingua Spanish has helped me expand my vocabulary and help with conversations and written correspondence. It's also helped me understand a lot of the signs and informational placards that are posted. It has really boosted my confidence when traveling abroad!"

"I have your Spanish/English and have been using it for many many years. I love this app so much that I tell everyone I possibly can about it. Every time one of my friends gets a new iPhone and asks me what apps they should get this is at the top of my list."

"I'm an undergrad linguistics major, and you're apps have helped immensely so far with learning foreign languages!"

"With an Italian father-in-law, a German mother-in-law, and Mexican parents, the languages fly fast and loose in my family! I am in need of help with my German, and your dictionary is a Great help!"

"Ive been learning Italian with the Ultralingua App and my study group have been impressed with the ability of quick searching whereas the traditional dictionaries take ages. The Conjugation has been an excellent way for a very quick verification."

Customer Reviews

Ultralingua Dictionaries

For a number of years I have used the Collins Pro Español–Inglés by Ultralingua as well as the Gran Diccionario Vox de la Lengua Español. Just recently I purchased the Ultralingua Collins Italian-English. The first two dictionaries are excellent and the latter is also good and has a surprisingly complete vocabulary. Naturally, as with all Ultralingua products the software is excellent. Perhaps most importantly, the Ultralingua customer support is unsurpassed. All three products are well worth the money.

Latest version doesn't work

I've used Ultralingua for years... going back to my old Palm device. The app was listed as an update in my iPhone so I did it. Now when I try to open it the app flashes on the screen and then goes to background. Clicking on it there results in the same issue. iPhone 6 with iOS 8.1.2. Rebooting phone did not help.
Also, the email I received from Ultralingua this morning mentioned v. 2.5 but the version number on iTunes is listed as 2.4.1
Hopefully Ultralingua will fix this soon. Otherwise my half dozen or more PAID dictionaries are useless

Complete and easy to use

The addition of an English dictionary
and thesaurus is great. But now I cannot access my French-Eng or Spanish-Eng dictionaries from the bookshelf. And trying to add the via the. Cloud produces no results
Major disappointment. Loss of a star.
End update.
And so much lighter than paper dictionaries! I use Spanish/English and French/English. I just added French/Spanish.
On the few occasions I have not been able to find a translation I have had to go into Google mode because they were not in my big paper dictionaries either.
