In the top right corner of the window, tap the "settings" icon (looks like a gear) to access the settings menu.
In the settings menu, you'll see three options for the Appearance of the app. "System", "Light" and "Dark". The system option is selected by default, which means Portals of Prayer will default to whatever the system default is for appearances on your device. However, if you want to override this, you can choose "Light" or "Dark" to make the Portals of Prayer app appear in Light mode or Dark mode, regardless of your system defaults.
