The app contains prayer of the rosary including modifications - mystery joyful, light, painful and famous. It also contains a crown to the Divine Mercy. In the app settings, you can set the night mode, prevent the screen from turning off, turn off sounds automatically, and use serif fonts for prayers, or set the midday prayer reminder and your own rosary prayer reminders for the day.
