About:
Whyfi is a macOS menu bar application that provides real-time monitoring and diagnostics for your Wi-Fi connection. It displays key metrics like signal strength, noise, and data rate, helping users quickly identify and troubleshoot network issues. Its primary value is offering detailed, at-a-glance network insights without needing to open System Preferences or terminal commands.
Key Features:
  • Real-time Wi-Fi signal and noise monitoring
  • Menu bar display for at-a-glance connection health
  • Detailed diagnostic information (channel, data rate, RSSI)
  • Historical graph of signal strength over time
  • Quick access to network scanner and connection details
Use Cases:
  • Diagnosing intermittent Wi-Fi dropouts or slow speeds
  • Optimizing router placement by monitoring real-time signal strength
  • Quickly checking network health without opening system settings
Alternatives:
  • iStumbler – More feature-rich wireless discovery tool, but not a lightweight menu bar monitor.
  • WiFi Explorer – Professional-grade Wi-Fi scanner with deeper analysis, less focused on simple menu bar monitoring.
