Can I sync my custom theme across different platforms like Android and iOS

General Theme Syncing

1. Obsidian App: For applications like Obsidian, syncing custom CSS themes between desktop and mobile versions is limited. Users have reported that while syncing is possible on Android, it requires additional steps on iOS, such as enabling hidden folder views to access theme files manually. However, many custom themes do not render properly on iOS due to font and UI element issues[1][6].

2. Flutter Applications: In Flutter development, you can create different themes for Android and iOS by detecting the platform at runtime. This allows for customized theming based on the operating system, but it requires separate implementations for each platform[4].

3. Microsoft SwiftKey Keyboard: Themes cannot be synced across Android and iOS platforms in Microsoft SwiftKey. Users must download their purchased themes separately on each platform as they are not transferable[8].

Specific Challenges

- iOS Restrictions: Apple's restrictions often prevent seamless syncing of custom themes from other platforms. Users might need to rely on workarounds or specific apps that allow theme customization[5][6].

- Theme Compatibility: Even when syncing is technically possible, many themes may not function correctly across platforms due to differences in rendering engines and available resources (like fonts) between Android and iOS[1][6].

Conclusion

While some applications allow for theme customization and syncing, the process can be complex and often requires manual intervention or specific tools, especially for iOS users. Therefore, if you are looking to sync custom themes across Android and iOS, be prepared for potential limitations and compatibility issues.
