Frequently Asked Questions

What versions of macOS are supported?
SideTime requires macOS 14.0 (Sonoma) or later. It's a native app, optimized for both Intel and Apple Silicon Macs.
Does SideTime affect system performance?
No! SideTime is incredibly lightweight, using less than 50MB of memory and minimal CPU. It's designed to run continuously without impacting your Mac's performance or battery life.
Can I customize the appearance?
Yes! Pick from gradient, solid, or tile themes, choose your colors, set the bar to live on the left or right edge, and make it thinner, thicker, more visible, or more subtle — all with simple sliders. Everything updates instantly so you can see what looks best.
How does calendar integration work?
SideTime reads from your local calendar (with your permission) and displays events as visual markers on the progress bar. No data is sent to external servers - everything stays on your Mac.
What about privacy?
Your privacy is paramount. SideTime runs entirely locally with no internet connection required. No analytics, no tracking, no account needed. Your data never leaves your Mac.
