Ultralingua is the best linguistic reference tool for a learner of any of their languages on offer, which includes Spanish, German, French, Italian, Portuguese and Esperanto. Ultralingua centralises definitions, verb conjugations, idioms and expressions, and even goes so far as to tell you how to pronounce numbers (an infinite numbers of digits long) in each language, and all of this for every language they offer, provided the respective dictionaries have been purchased within the app. Ultralingua also pays a lot of attention to detail by allowing you to favourite words, to change the font and its size, and, regardless of the current translation direction (i.e. Spanish to English or English to Spanish), it allows you to search for any word in either of the languages, or for any conjugation of any verb in either language. For those with an unsteady typing finger, suggestions are always provided. I personally would like the user interface of the overall environment to improve in some regards, but I am also sure that this will happen over time. I assure you that it isn’t enough to hinder any exploration into your newly found language learning experience.
