This app is the Śrīmad Bhāgavatam in Russian: a translation from the Sanskrit made with the commentaries of the acharyas, with Devanagari, transliteration, word-for-word meanings, the acharyas' commentaries and narration of the verses. The text and narration are in Russian only. The book is being published in stages.
The book comes out in stages: first the verses of a canto, then the narration of the verses and the commentaries. New parts arrive in app updates, and your progress is kept.
Open a chapter and tap the round button at the bottom. The moon icon in the player sets where to stop: at the end of a chapter, at the end of a canto or with a sleep timer. Every verse of Canto 1 is narrated now; the commentaries are not narrated.
No. The text and narration are inside the app.
