Real-time monitoring
Signal, latency and loss tick live. Glanceable status icon in the menu bar, full popover on click.
WiFi Checker
Network Diagnostics · macOS
Real-time Wi-Fi health, on the menu bar.
Signal strength, latency, packet loss, DNS resolution time, throughput. WiFi Checker watches your network in the background and tells you the second something goes sideways — before you start blaming Zoom.
What it watches
Five numbers that explain almost every problem
Every metric updates live. No graphing dashboards to interpret — just the numbers that matter, in plain sight.
RSSI
Signal strength
dBm + bars, with a colour-coded threshold ladder.
Ping
Latency
ms to your gateway and to the public internet.
Loss
Packet loss
% over a rolling window. Where lag actually comes from.
DNS
Resolution time
ms to resolve a known name. Catches DNS-only outages.
↕ Mb/s
Speed test
One-click download / upload from a nearby endpoint.
Features
Diagnostics, not dashboards
Built to answer one question fast: "is the network the problem?"
Network diagnostics
Router probe, internet probe and DNS probe — labelled so you know which leg is failing.
Speed testing
One-click symmetric speed test. Result history kept locally so you can spot regressions.
DNS analysis
Resolution time and provider breakdown. Catches the "internet is fine but Slack won't load" class of bugs.
Threshold notifications
Get notified when signal drops, packet loss spikes, or DNS goes south.
Privacy-first
Everything runs locally. No analytics, no account, no third-party servers seeing your network state.
