Currently, Nova does not have a built-in dark mode setting within the app.
The app uses a single light theme, and there isn't an option in Settings to switch to dark mode at this time.
On some devices, your system-wide dark mode may affect certain elements, but a dedicated in-app dark mode is not available.
If dark mode is something you'd like to see in a future update, we'd love to hear your feedback, please reach out to our support team at [email protected]
