Use cases
- Your home or office internet suddenly stops working, and you want to know whether the router or ISP is more likely involved.
- Your phone is connected to Wi-Fi, but you cannot tell whether the local network or the internet is failing.
- The connection is intermittent, and you want to know whether local or internet instability is more likely.
- You are sharing a hotspot with a computer or tablet and want a quick check of the current link.
How it diagnoses
The app combines the current system network state, a local anchor probe, and HTTPS internet probe results to produce a plain-language conclusion. Technical metrics are still available for review, but they are not the focus of the home screen.
What it does not do
The current version does not provide always-on background monitoring, VPN, proxy, packet capture, port scanning, traceroute, whois, or router management. It also cannot modify system network settings for you.
Privacy posture
The current version runs offline by default and does not require sign-in. Diagnosis history and preferences are stored locally. During diagnosis, it reaches the configured local anchor and internet probes; if it needs to show the current egress ISP, it may query public IP and RDAP ownership services.
