Hotspot Meter — Track Wi-Fi and hotspots

什么是 Hotspot Meter — Track Wi-Fi and hotspots？

Hotspot Meter is a free macOS menu-bar app that shows exactly how much data each Wi-Fi network and phone hotspot uses. See live download and upload speeds, track session and per-network totals, review usage history, and get an alert before reaching your data cap. Everything runs locally on your Mac: no analytics, no accounts, and no personal data collected or transmitted.
