DM Digital Rain: A Falling-Code Screen Saver for Your Mac
Streams of glowing characters pour down a black screen, drawn live and never repeating. DM Digital Rain is a real macOS screen saver, and an app that plays the same rain on your Mac, iPhone and iPad.
Watch it run
The opening as the screen saver starts: black, a single stream, a few more, then the full rain. After that, the Rainbow colour, Binary glyphs, and a colour of your own.
Try it here
This is the same rain, running in your browser. Change the colour, glyphs, speed, density and size, replay the opening, or go full screen.
A screen saver, set up in a minute
Open the app and click Install Screen Saver…. macOS asks once, then you pick DM Digital Rain under Other in System Settings › Wallpaper › Screen Saver… (or System Settings › Screen Saver on macOS 14 and 15). When your Mac goes idle, the screen fades to black, a single stream starts to fall, a few more join it, and then the rain fills every display. Test Screen Saver in the app starts it right away.
Make it yours
Eight colours including Rainbow, or any colour you like from the colour picker. Classic glyphs (mirrored katakana and numerals), Binary, or Latin letters. Sliders for speed, density and glyph size. Set them in the app, or from Options… in System Settings.
Smooth on every display
The rain is drawn on your Mac’s graphics chip at 60 frames per second, so it stays smooth across several large displays and barely touches the processor. It runs on Apple silicon and Intel Macs.
Coming to iPhone and iPad
iOS has no system-wide screen saver, so the iPhone and iPad app, coming to the App Store, starts the rain as soon as you open the app and keeps the screen awake while it runs: a good fit for a stand, a spare device, or a display on a shelf. Tap the screen for the same style options.
Private by default
No account, no ads, no network connections, no analytics. Your style choices stay on your device. See the privacy policy, and the support page for set-up help.
