We believe, that the best way to study a foreign language is to study it using educational materials written in the target language. The example of such materials constitute our Lingo Learning Cards available in 3 applications which cover the following topics: Business English, Phrasal Verbs and English Tenses. Learning Cards improve users vocabulary and language patterns, consolidate their knowledge and all these in a convenient, extremely natural user interface. Applications are currently available for iOS. All 3 apps were developed in only 4 weeks by a single iOS developer.
