In the app you can adjust the paper, ink, draw speed, line length and seeds. It runs natively on your Mac, drawn live in real time – no video, never quite the same twice.

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