What users say
Loved by power users
"Finally a system monitor that doesn't look like it's from 2005. The acrylic overlay is gorgeous and it uses almost no resources."
"I switched from XMeters because I wanted a floating overlay instead of being stuck in the taskbar. PulseBar is exactly what I needed."
"Per-core CPU bars are a game changer for my video rendering workflow. I can see instantly which cores are maxed out."
