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

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