Walk-and-paint Wi-Fi survey
Tap a starting point, walk your home, and watch a live heatmap paint itself onto a floor plan. No extra hardware. No router login. Just your iPhone.
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 Wi-Fi heatmap. Survey any room in minutes, get a clear report on where your signal is weak, and learn exactly what to do about it.
Free Speed, Signal & Devices tabs. WiFi Buddy Pro is $9.99/year or $5.99 every 6 months. Cancel anytime.
A real report, not just dots
Every survey produces a graded coverage report — where your dead zones are, how bad they are, and a personalized list of what to try first.
Know what's on your Wi-Fi
See every device on your network, automatically named and labeled. Mark the ones you trust, and get an alert the next time something new shows up.
A speed test you can trust
Real download, upload, ping, and jitter — measured the way your apps actually use your connection. No vague bars, no number tricks.
Privacy by design
No accounts. No servers. No analytics. Your surveys, device lists, and chat history stay on your iPhone — full stop.
A clear view of your network
A simple ISP → Router → Device picture, with a live health check on each hop. One glance tells you whether the slowdown is your home or your provider.

The whole home, one walk.
