WiFi Heatmap - Signal Map

Is your WiFi letting you down in certain rooms? Buffering videos in the bedroom, dropped calls in the kitchen, or no signal in the basement?
WiFi Heatmap is the easiest way to create a WiFi coverage map of your home and find every dead zone in minutes — no technical knowledge needed.

Turn your phone into a WiFi signal strength mapper. Walk room by room, take quick measurements, and see a color-coded WiFi heatmap showing exactly where your signal is strong and where it falls apart. Then get smart recommendations to fix the problem.

Setup in under 2 minutes:
Most WiFi survey apps make you import a floor plan, calibrate, set scale, and draw walls before you can start. WiFi Heatmap skips all of that.

1, Pick a floor plan template that matches your home
2, Slide to set the number of rooms (2 to 6)
3, Name your rooms and mark where your router is
4, Walk to each room and tap Measure
5, View your WiFi coverage map as a color-coded heatmap

No drawing, no calibration, no import. Just pick, tap, and walk.

Find your wifi dead zones:
See your WiFi signal strength at a glance. Green means excellent coverage for 4K streaming and gaming. Yellow is good for HD video and calls. Orange means browsing may lag. Red marks a dead zone where your WiFi drops entirely. No more guessing why WiFi is slow upstairs or weak in the bedroom.

Smart wifi recommendations:
WiFi Heatmap goes beyond any other WiFi signal map app. It does not just show you a picture — it tells you what to do:

Router relocation — If your router is at the edge and rooms have poor WiFi coverage, the app suggests a more central position.

Channel optimization — If your WiFi channel is crowded with neighboring networks, the app recommends switching to a less congested channel.

Band switching — If your router supports 2.4 GHz and 5 GHz, the app shows which rooms can use the faster band and which need better range.

Repeater placement — If a dead zone exists that moving your router cannot fix, the app suggests where to place a WiFi extender or mesh node.

Every recommendation includes a priority level so you know what to fix first.

Wifi health score:
WiFi Heatmap calculates a score from 0 to 100 based on signal strength across rooms, weakest-point severity, and channel interference. One number that tells you how well your WiFi covers your home. Re-scan after changes to track improvement.

Flexible floor plans:
5 layout templates designed for real homes:

Linear — rooms in a row, typical for apartments
Corridor — rooms along a hallway
L-Shaped — two wings, typical for family houses
Open Center — large living area with surrounding rooms
Outdoor — for gardens

Each supports 2 to 6 rooms. Multi-floor support lets you scan every level in one project.

Detailed signal data:
Tap any room to see WiFi signal strength in dBm, band (2.4/5/6 GHz), channel, link speed, ping, and neighboring network count.

Save and compare:
Every WiFi survey saves automatically. Re-scan after moving your router or adding a repeater and compare before-and-after WiFi coverage maps side by side.

Built on proven technology:
Developed by the team behind WiFi Analyzer, trusted by hundreds of thousands of users for reliable WiFi signal testing. The measurement engine is field-tested across thousands of real environments.
