Gora Academy teaches Russian, Serbian, Croatian, Montenegrin and Bosnian with clear explanations of how the languages actually work.
Instead of only drilling isolated words, learners build useful sentences through structured lessons, interactive exercises, native-speaker audio, vocabulary review, short stories, games and guided speaking. It is especially useful for Balkan languages that mainstream apps often overlook.
Gora is available on iPhone, Android and the web, with a seven-day free trial.
