Библия: Синодальный перевод is an iPhone application that provides access to the Bible in Russian, Church Slavonic, and Greek. The app includes the Synodal translation (1876), the Elizabethan Bible (1751), and the Greek text from the Septuagint and the New Testament editions by the Constantinople Patriarchate in 1904.

The app allows users to save their current book and chapter across devices using the same Apple ID account. However, syncing can be disabled in the iCloud settings. With a focus on education and reference, this app is a valuable resource for those interested in studying religious texts in multiple languages.

Please note that the app does not align the chapters in the Septuagint with the verses in the Slavonic translation in all instances. This may affect the reading experience for some users.
