We’ve been expanding dark mode support across our mobile apps, and both Android and iOS now have a new in-app toggle for even more control over your preferences.
How to set your preference: Head to the Appearance section in your account tab and choose between light mode, dark mode, or match your system settings. If you don’t change anything, Splitwise will automatically follow your device’s settings by default.
How to get access: Update to the latest version of the Splitwise app to access dark mode, the in-app toggle, and all the newest features.
