Draw your floor plan, walk each room collecting signal measurements, and HeatFi generates a vivid WiFi heatmap — so you know exactly where your dead zones are and how to fix them.
No networking degree required. HeatFi guides you through the whole process in under 10 minutes.
Draw or import your 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.
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.
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.
The same screens you'll find on the App Store — floor plans, walk surveys, and finished WiFi heatmaps.
HeatFi is free to download on iOS and Android. Start mapping in under a minute.
