In the app you can choose the colours and bead width, and turn the seconds and digits on or off. It runs natively on your Mac, drawn live in real time – no video, never quite the same twice.

Abacus Clock FAQ
How do I set Abacus Clock as my screensaver on a Mac?
Install SCRNSVRS free from the Mac App Store, select Abacus 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 Abacus Clock as a live wallpaper?
Yes. Click Set as Wallpaper in SCRNSVRS and Abacus Clock plays on your desktop behind your windows and icons. You can use it as screensaver and wallpaper at the same time.
Is Abacus Clock free?
Yes. Abacus Clock is Free Forever in SCRNSVRS – no account, no ads, no subscription.
Is Abacus Clock a video loop?
No. Abacus 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 Abacus 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 Abacus Clock costs next to nothing in everyday use.
Which Macs does Abacus Clock run on?
Abacus Clock needs macOS Tahoe 26 or later.
