How it works

Three steps to total WiFi clarity

No networking degree required. HeatFi guides you through the whole process in under 10 minutes.

Draw or import your plan

Step 01

Draw or upload your floor plan

Sketch your layout freehand inside the app, import an image of your blueprint, or snap a photo of a printed plan. HeatFi scales and aligns it automatically so you're ready to survey in seconds.

Step 02

Walk your home & collect measurements

HeatFi's guided route tells you exactly where to walk next. Move through each room and tap "Take Sample" — the app reads your device's WiFi signal strength in real time and pins each reading to the map.

Step 03

Get your heatmap — instantly

HeatFi interpolates your data and renders a colour-coded heatmap with per-room signal scores. Red is strong, blue is a dead zone. See exactly where to move your router, add a mesh node, or call your ISP.
