In the app you can adjust the colours, ratio and speed. It runs natively on your Mac, drawn live in real time – no video, never quite the same twice.

Chord Sweep FAQ
How do I set Chord Sweep as my screensaver on a Mac?
Install SCRNSVRS free from the Mac App Store, select Chord Sweep 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 Chord Sweep as a live wallpaper?
Yes. Click Set as Wallpaper in SCRNSVRS and Chord Sweep plays on your desktop behind your windows and icons. You can use it as screensaver and wallpaper at the same time.
Is Chord Sweep free?
Chord Sweep is included in SCRNSVRS Unlimited. It's free for your first 7 days; after that Unlimited is $1.99/month or $9.99/year (€1.99/month or €9.99/year) for every screensaver, including new ones. It can also come up in Free this month, when 25 premium screensavers are free for everyone.
Is Chord Sweep a video loop?
No. Chord Sweep 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 Chord Sweep 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 Chord Sweep costs next to nothing in everyday use.
Which Macs does Chord Sweep run on?
Chord Sweep needs macOS Tahoe 26 or later.
