Frequently asked questions
Can NetPulse diagnose why Mac internet is slow?
NetPulse helps narrow down common causes by showing live speed, latency, packet loss, IP details, traffic totals, and optional per-app traffic.
Can it tell whether slow network is caused by one app?
Yes. After optional Network Extension approval, the Processes view can show per-app live upload and download speed.
Does NetPulse replace a full network diagnostic suite?
No. It is intentionally minimal and focused on everyday network visibility from the menu bar.
