The UniLex App can lookup terms in reference works like dictionaries, glossaries and term bases. It is possible to import own reference works. For this purpose you have to provide a csv file using two columns. The content of the first column is the search term, the content of the second column is the entry representation in html. UniLex can be extended by professional dictionaries via in-app purchases. You find the according dictionaries at the app store. Properties: - import your own reference works. - search in professional dictionaries and special dictionaries. - lookup at all reference works at the same time. - restrict search to language pairs. - use different search options. - filtering function to summarize search results in a list of results. - hyperlinks enable to navigate back and forth between the articles of the reference works. - display of a list of search results with an up/down page scroll to further results. - two-list-display - headword list and search results - in the iPad-app. - offline usage: the UniLex app needs to be downloaded only once.
