## What is WiFi Buddy?

Wi-Fi Buddy turns your iPhone into a real Wi-Fi diagnostic tool - the kind professionals charge for, but designed for normal people in their own homes.

Walk your space with the camera up. As you move, Wi-Fi Buddy paints a live heatmap of your signal quality onto a floor plan, so you can see exactly where streaming buffers, calls drop, and games lag. No extra hardware. No router login required.

WHAT YOU GET

• AR Wi-Fi Survey — Walk your home and watch a real heatmap appear on the floor plan as you go. Spots are color-coded by latency, and a blue trail shows your path so you can re-walk weak rooms.

• Smart Insights — When you stop, Wi-Fi Buddy grades your network A through F and tells you what to do next: move the router, add a mesh node, switch this device to 5 GHz, change to a less-crowded channel. Best and worst spots are pinned right on the map.

• Live Speed Test — Download, upload, ping, and jitter measured against the nearest Cloudflare server. We even tell you which Cloudflare city your test ran through, so you can spot when your ISP is routing you cross-country.

• Live Network Topology — See your ISP, router, and device in real time, with live latency on each hop and animated packet flow so you know which leg is the bottleneck.

• Who's On My Wi-Fi? - Eight-layer device discovery (Bonjour, SSDP/UPnP, port fingerprinting, hostname, HTTP, MAC vendor lookup) puts a real name and brand on every device on your network. Trust the ones you recognize, get notified when a new device joins, and rename them however you want.

• Klaus, your Wi-Fi sidekick - Ask Klaus anything about your home Wi-Fi. Why is gaming slow at night? Mesh or extender? 2.4 vs 5 GHz? Klaus has answers tuned to real homes, not jargon.

### 5/5 — Best wifi survey app

*2026-05-07*

I was having issues with my internet at home and talking to my internet supplier was no help over the phone. Thankfully I found this app and was able to seek where my internet was malfunctioning. 

The survey function was extremely useful amd easy to use. Additionally, the WiFi report portion is 10/10. I was literally able to see why while playing only I had lag. Highly recommend this app to anybody having internet issues.

**Developer response:** Thanks for using Wi-Fi Buddy! I am glad we were able to meet your needs!
