Code Rain Clock
Read full descriptionHide full description
A Matrix-inspired digital rain clock for iPhone and iPad. Turn your device into a cyber desk clock with cascading code and a clean digital time display — perfect for focus sessions or winding down. Customize the clock’s color, size, position, and 12/24-hour format, or hide the clock entirely and enjoy the rain alone. Your chosen color applies across the digital rain so you can create your own cyber aesthetic. The screen stays awake while the app is open, so you can leave it running as a clock. For longer use, we recommend lowering screen brightness.
