## What is NetDoctor?

Why is my Wi-Fi slow? NetDoctor finds out.

One tap runs a full check-up of your home network and tells you, in plain language, whether the problem is your Wi-Fi, your router, your internet provider or DNS — and what to do next.

DIAGNOSIS, NOT JUST NUMBERS
• A health score with the evidence behind it
• Clear answers like "Your Wi-Fi is fine. Your DNS is slow."
• Confidence level and step-by-step fixes

WHAT NETDOCTOR CHECKS
• Phone → router latency, jitter and packet loss
• Internet latency and stability
• DNS speed compared with Cloudflare, Google and Quad9
• Download and upload speed
• Sign-in pages, VPN, IPv6 and Low Data Mode

WI-FI OR PROVIDER? WE CAN TELL
Run the same test on Wi-Fi and on cellular to see where the problem really is.

FIND WEAK SPOTS AT HOME
Wi-Fi Health Map: test each room and see which ones need help — based on real performance, not just signal bars.

SEE EVERY DEVICE ON YOUR NETWORK
Router, Apple TV, printers, speakers, smart home and more. New devices are highlighted — without scary "you've been hacked" alarms.

LAG UNDER LOAD
The bufferbloat test explains "500 Mbps, but my game still lags."

HISTORY
See when your network got worse: "Health dropped from 94 to 61."

PRIVATE BY DESIGN
No account. No cloud. No ads. No tracking. Your diagnostics stay on your iPhone.

NETDOCTOR PRO — PAY ONCE
Wi-Fi Health Map, lag-under-load test, DNS Compare, unlimited history and trends, device naming and shareable reports. One-time purchase, no subscription. Try each Pro test once for free.

Speed tests use Cloudflare's public speed servers and use mobile data when you're on cellular.
