WiFi Buddy

Built for iPhone & iPad · iOS 17+

See your Wi-Fi.
Walk your home.
Find every dead zone.

WiFi Buddy turns your iPhone into a walking heatmap. Survey any space in AR — no extra hardware — and get a graded report telling you where your signal dies and what to do about it.

Free Speed, Signal & Devices tabs. WiFi Buddy Pro from $3.99/mo with a 3-day free trial.

AR walk-and-paint survey

Tap a start point on the floor plan, walk the space, and watch signal strength paint itself onto a live heatmap. ARKit world tracking — no extra hardware, no router login.

Insights engine, not just dots

Every survey produces a graded report — coverage breakdown, dead-zone clusters, jitter analysis, and a personalized fix list (mesh, channel change, router relocation).

Identifies every device

An 8-layer scanner (Bonjour, SSDP/UPnP, port fingerprint, ARP-table MAC + OUI lookup, reverse DNS, more) labels every gadget on your Wi-Fi — even the ones using MAC randomization.

Real speed test, real ISP context

Cloudflare-backed download/upload with multi-stream throughput, plus a server-selection step that flags when your ISP is routing to a far-off POP — the AZ → DFW failure mode that makes ISP apps look fast and yours look slow.

Privacy by construction

No accounts. No servers. No analytics. Surveys, device lists, and chat history live only on your device. Speed-test traffic is the only data that ever leaves your phone.

Live network topology

ISP → Router → Device, each hop with its own real-time TCP probe and traffic-light health classification. A glance tells you whether the slowdown is upstream or inside your home.

Meet Klaus

Klaus, your AI Wi-Fi sidekick.

Klaus is a pixel-art Wi-Fi assistant living on the Signal tab. Ask him anything — from “why is my 5 GHz slower than 2.4?” to “should I buy a mesh system?” — and get a plain-English answer pulled from a curated knowledge base of the questions we hear most often.

  • 24 hand-written Wi-Fi answers
  • Coverage, gaming, streaming, security
  • Suggested follow-up questions
  • Pro unlocks unlimited chat

Free accounts get one question per install. WiFi Buddy Pro unlocks unlimited chat with Klaus from $3.99/mo.

    Devices

    8-layer device discovery names every gadget on your Wi-Fi.

The whole home, one walk.

Most "Wi-Fi analyzer" apps show a single number for the spot you're standing in. WiFi Buddy plots latency at every step on a live floor plan, then tells you in plain English where the weak spots are and what to change first. It's the difference between a thermometer and a weather forecast.

  • A–F graded coverage report
  • Dead-zone clustering with room labels
  • Jitter + p95 latency, not just averages
  • Re-survey reminders at 30 / 90 / 180 days
  • New-device alerts on trusted networks
  • Mesh vs extender vs reposition guidance
