"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."

"This app simply works. Its not filled with gimmicks, its intuitive, its the best!"

"Working in translation, your apps offer me immediate access to a wealth of information whenever I am on the go. Keep up the good work!"

The Best Dictionary

After upgrading iOS from 8.3 to 9.1 this app crashed when launched. I contacted support and for the first time ever, they did not respond. After several days I contacted them again and they responded, telling me to uninstall and reinstall the app, which I did. This deleted all my purchased dictionaries. Their instructions stated that if this happened I could have the app reinstall all purchased dictionaries. This does not work. I contacted support again and again no response. I contacted them AGAIN and now nothing but silence. So I'm left with an app with none of the dictionaries I that I've paid for. From 5 stars to 1.
This app is by far the best German/English and French/English dictionary I have ever used. It is comprehensive and gives plenty of examples of word usage.

You can search for a conjugated verb or a verb in any tense and it will locate it, give you the definition and steer you to the infinitive. From there you can get all conjugated forms of the verb.

I use this app every day, multiple times per day. It is the most used app on my iPhone and it is the only app about which I have no issues or complaints.

Don't know what I would do without it!

I am currently visiting Brazil and I am learning Portuguese. I consult me English/Portuguese and Spanish/Portuguese dictionary many times a day! Thank you for making the Spanish/Portuguese dictionary.

Reading another review...yes, the pop-up menu that you have to choose every time is annoying. I like that you can tap on the name of the dictionary you are using and it gives you all your options.

The best multilingual dictionaries on iOS

I am bilingual in Spanish and use the app for work. I'm also a language hobbyist and love the ability to search all dictionaries at the same time to define unknown words and study their origins. I have tried many other English to foreign language apps and none compares to the completeness, ease of use and accuracy of Ultralingua. The monolingual Spanish and French dictionaries are also the best on iOS.
