Wiser supports dark mode based on your device settings. If your phone is set to dark mode, the app will automatically switch to dark mode as well.
Alternatively, while reading a book summary, you can manually switch to a dark background:
Open any book
Tap “Read”
Tap the “Aa” icon in the top-right corner
Choose the black background option from the appearance settings
This way, you can read more comfortably in low-light environments.
