A lightweight macOS menu bar app that monitors network latency with real-time sparkline visualization.

MacPing continuously pings google.com and displays the last 60 ping results as a pixel-based histogram in your menu bar. Taller bars = higher latency. Updates in real-time. Bars above 100ms shown in red.

Click the menu bar icon to access:

• Show Details - Opens a detailed latency graph window with live updates
