A. If Dippy does not have a built-in dark mode, you can enable dark mode at the system level on your Android device. Go to Settings > Display > Dark theme and enable it. This may not change the app's interface but can reduce eye strain when using the app in low-light conditions.

B. Alternatively, you can use a third-party app that forces dark mode on all apps. Search for 'dark mode' apps in the Google Play Store, but be cautious and read reviews to ensure they are safe and effective.
