The best multilingual dictionaries on iOS

I am bilingual in Spanish and use the app for work. Im 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.
