Cyrillic is a simple Russian application. Think of it as an ABC book for Russian. It teaches reading and writing in Russian. In addition, the application contains quizzes, lessons, history, interesting facts and memory cards for easier learning. This is probably not great as a primary source of research. However, this combined with Busuu, Duolingo, Memrise or Rosetta Stone will make a good punch for beginners. Intermediaries and experts may already know these things. So this one is just for beginners.

Rosetta Stone is one of the biggest names in the field of language learning. They support two dozen languages and yes, one of them is Russian. This section focuses on basic vocabulary and conversational Russian. It builds on that foundation and continues from there. It's a pretty effective method, even if it's a bit more traditional than a method like Memrise or Drops. The app also includes offline support, a speech recognition system, and plenty of hands-on lessons. This is probably the most expensive app on this list. However, it's really only for serious learners.
