Colorful Blink Notification Light is a free personalization app developed by SoftWiz for Android 13.0 and above. The app provides a solution for missed LED notifications by enabling users to receive colorful notifications instead. With the app, users can customize their notification light to their preference, including the color and size of the light.

To use the app, users need to disable any battery optimizations for the app and provide notification permission. They can then select the apps they want notifications for and customize the color and light size. For MIUI devices, users need to ensure that AutoStart is enabled in the app info and "Show on Lock Screen" is enabled in other settings.

Overall, Colorful Blink Notification Light is a simple and effective app for users who want to add some color to their notifications.
