The time in glowing LEDs – for people who read binary at a glance.
Hours, minutes and seconds as rows of glowing LEDs that fade on and off like real ones behind a diffuser.
Choose the classic column layout, one column per digit with bit values 8-4-2-1 (binary-coded decimal), or plain binary rows for hours, minutes and seconds. Pick red, green, blue, amber or white LEDs, 12- or 24-hour time, and switch the bit values and digit readout on to learn as you watch – or off for pure LEDs. Like every clock in SCRNSVRS, you can zoom it and move it anywhere on the screen.

Binary Clock FAQ
How do I set Binary Clock as my screensaver on a Mac?
Install SCRNSVRS free from the Mac App Store, select Binary Clock in the library and click Set as Screensaver. macOS starts it whenever your Mac is idle, exactly like a built-in screensaver.
Can I use Binary Clock as a live wallpaper?
Yes. Click Set as Wallpaper in SCRNSVRS and Binary Clock plays on your desktop behind your windows and icons. You can use it as screensaver and wallpaper at the same time.
Is Binary Clock free?
Yes. Binary Clock is Free Forever in SCRNSVRS – no account, no ads, no subscription.
Is Binary Clock a video loop?
No. Binary Clock is rendered live on your Mac with Metal, so it never repeats and stays sharp on any display size. The clip on this page is a screen recording of the real thing.
Will Binary Clock slow down my Mac or drain the battery?
No. SCRNSVRS drops to 30 fps on battery and stops rendering when the wallpaper is covered by a full-screen app, so Binary Clock costs next to nothing in everyday use.
Which Macs does Binary Clock run on?
Binary Clock needs macOS Tahoe 26 or later.
