▶ Run approximate speed tests for download, upload, latency and jitter
▶ Use DNS lookup, DNS speed test, port scan and Whois / IP info tools
▶ Discover local Bonjour services such as web, printer and media services
▶ Save diagnostic history locally
▶ Export reports as PDF, CSV or text
▶ No account required and no cloud upload

Use it to understand your current connection, find reachable devices on your local network, test internet speed, check TCP latency, resolve DNS records, scan common ports, look up IP/domain information, browse Bonjour services, and export local diagnostic reports.

Whether your Wi-Fi feels slow, a device is hard to find, DNS is acting strange, or you simply want a quick network check, Network Doctor gives you the essential tools in one simple app.

Key Features

◉ Network Health Dashboard
View your current connection, internal IP, public IP, DNS status, latency, and latest speed test result.

◉ LAN Scanner
Find reachable devices on your local network using TCP connection probes. See detected services such as web, file sharing, and other reachable TCP ports.

◉ Speed Test
Measure approximate download speed, upload speed, latency, and jitter using real network data.

◉ TCP Ping / Latency
Check connection timing to a host and port. Designed for iOS using TCP connection timing instead of ICMP ping.

◉ DNS Lookup
Resolve A, AAAA, MX, TXT, and NS records for domains.

◉ DNS Speed Test
Compare DNS-over-HTTPS response timing and see which resolver responds faster.

◉ Port Scan
Check common, web, mail, or custom TCP ports for a specific host.

◉ Whois / IP Info
Look up domain and IP information for quick network reference.

◉ Bonjour Browser
Discover local Bonjour services such as web, printer, media, and file sharing services.

◉ History & Reports
Save diagnostic records and export reports as PDF, CSV, or text through the iOS share sheet.

◉ Privacy Friendly

Network Doctor does not require an account. Reports are generated locally. LAN scan and Bonjour browsing only start when you choose to run them. The app does not collect MAC addresses or vendor tracking information.

Network tests may use network data, and speed tests send random test data only for measurement. Results are approximate and can vary based on your Wi-Fi, router, ISP, endpoint availability, and current network conditions.
