PRIVACY FIRST
Traffic is measured by a local network extension and shown only on your Mac. NetTraffic only counts bytes - it never blocks connections, and nothing is uploaded, collected or tracked.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Traffic Details is now a sortable table: Download, Upload and Total columns — click any column header to sort
• Each row shows a second line: the app's process name, or the host's country and network
• New filter: All / Apps / System / Command Line
• Fixed: network monitoring no longer asks you to click Enable every time you reopen the app
• Steadier Live view: speeds are averaged over the last 5 seconds
• More proxy apps recognized (Karing, FlClash…) to avoid double-counting
• Fixed the Safari icon showing an alias arrow
