NetCheck sits quietly in your menu bar as a single dot — green when you have internet, grey when you don't.
Unlike the Wi-Fi indicator built into macOS, NetCheck confirms actual internet access with a lightweight network probe. Your Wi-Fi can show full bars while your router has no connection to the internet. NetCheck catches this and alerts you immediately.
• RESPONSE TIME METER
Open the popover to see your connection quality at a glance — a live bar shows your response time (with DNS and route split) and updates automatically while you watch.
• INSTANT NOTIFICATIONS
Get notified the moment your internet drops, and again when it comes back. Never wonder why a page isn't loading.
• ISP IDENTIFICATION
See your current ISP or Wi-Fi network name displayed directly in the popover, updated automatically on each connection.
• CUSTOMIZABLE CHECK INTERVAL
Choose how often NetCheck probes: every 5 seconds, 15 seconds, 30 seconds, 1 minute, 2 minutes, or 5 minutes.
• STAYS OUT OF YOUR WAY
No dock icon. No Cmd+Tab entry. Just a dot in the corner of your menu bar.
• LAUNCH AT LOGIN
Enable once and NetCheck monitors your connection from the moment you log in.
• IN YOUR LANGUAGE
NetCheck is fully localized into 34 languages — if your Mac speaks it, NetCheck speaks it. Right-to-left layouts included.
——— NETCHECK PRO — ONE-TIME PURCHASE ———
Unlock advanced features with a single, one-time payment. No subscription. Yours on every Mac you own.
• OUTAGE ALERTS ON YOUR IPHONE
Not at your Mac when the internet drops? Get a push notification the moment it's back — with exactly how long you were down. Works with ntfy.sh (free), Pushover, or your own webhook.
• BUILT-IN SPEED TEST
Run a real internet speed test — download, upload, idle latency, and responsiveness — right from the menu bar. No separate app, no browser tab required. Turn on automatic testing (daily, weekly, or monthly) to track your connection over time without lifting a finger.
• NETWORK HISTORY & RELIABILITY SCORE
A timestamped log of every connection event — drops, restores, and outages — with a scored reliability summary (0–100) across availability, stability, and latency.
• CUSTOM PROBE ENDPOINTS
Add up to 2 custom HTTPS URLs. NetCheck checks them alongside every connection probe and shows live reachability and latency directly in the app.
• CSV EXPORT
Export your full connection history — every outage, timestamp, and duration — as a CSV file. Useful as evidence when reporting recurring issues to your ISP, or simply for your own records.
• SHORTCUTS INTEGRATION
Automate your network checks with two App Shortcuts actions: "Get Connection State" and "Run Connection Check."

Added a quick way to open Wi-Fi Settings from the No Internet notification. NetCheck now also supports macOS Sequoia (15) and later — not just the newest macOS.
