Православное богослужение (Orthodox Worship) is a free Android application developed by Медиапроект s-t-o-l.com. This app consists of two main sections: "Calendar" and "Worship." The "Calendar" section includes readings used during worship in Russian translation, including the parables for the evening service, a full Orthodox monthly prayer book with the lives of selected saints, the main hymnography of the Orthodox Church in Russian translation, texts for useful home reading from the Holy Scriptures, and more. The "Worship" section includes the order of services of the Russian Orthodox Church in Church Slavonic and Russian translations. The application has a user-friendly design, and users can change the font size of the text, which is essential for the older generation. The content of the application is continually updated, and the pleasant design makes it easier to enter into the spirit and meaning of Orthodox worship.
