Love this Russian app and use it every chance I get to teach my children and brush up on my pronunciation! Highly recommended for beginners and children - the current version (2015/16) has been updated to correct some words/translations so the voice is noticeably different and loses quality in sound - some words have to be refreshed to hear them during the questions. This review is for the purchased Russian Flash Cards, only. I cannot attest the same for other languages, versions, or apps, however. It has not crashed yet and has been reliable, so far.
