A lightweight, resource-efficient app for monitoring WiFi connections, network latency, and connection health across all your devices.
Interface
Instant insight into your network health across all your devices.
Features
NetJolt gives you the network visibility you need without the complexity you don't.
Real-time signal strength, stability scores, and WiFi health grades at a glance from your menu bar.
Monitor ping latency to your gateway, Cloudflare, and custom servers with live sparkline charts.
Run download and upload speed tests without leaving your menu bar. Track results over time.
Track DNS server latency and identify resolution bottlenecks slowing your browsing.
See which WiFi channels are congested and get recommendations for the least crowded ones.
Built with Swift and SwiftUI. Sits quietly in your menu bar using minimal CPU and memory.
Follows your system appearance preference or choose your own. Looks great in both dark and light mode.
Detects active VPNs and Tailscale tunnels, identifies your exit node, and compares tunneled latency against your raw connection.
One-click traceroute, port checks, and MTU tests to pinpoint exactly where traffic breaks between you and the destination.
