BL Emerald Theme is a personalization app that allows users to customize the look and feel of BIG Launcher. This theme can be used with the latest version of BIG Launcher or BIG Launcher FREE DEMO. It is important to note that this is not a standalone app and themes can be memory intensive, so it is not recommended to use them on low-end devices.

To apply the BL Emerald Theme, users need to go to Preferences, then Appearance, and select the theme from the options available. Additionally, users can use custom icons by going to Preferences, then Customize buttons and screens, and choose from the internal icons or the theme icons themselves.

For more information, users can watch the video tutorials or read the user manual on the BIG Launcher website. In case of any problems, users can contact the developer at

Overall, BL Emerald Theme is a great option for users who want to personalize their BIG Launcher experience and add a touch of elegance to their device.
