About this app

If you have a home or office wireless network and you want to see exactly what the quality of coverage your Wi-Fi access point provides, you might need a smart wifi analyzer app; WiFi Heatmap will be a big help in your job.

The app can quickly draw a heat map so that you can easily and immediately see where Wi-Fi signal strength is weak.

As WiFi Heatmap features an automatic movement detector; all you are requested to do is walking around with your phone and the app will take care of the measurements.

Note: automatic movement detection requires a smartphone with both accelerometer ad magnetic sensor support, otherwise, only manual scan mode will be available.

If you are worried about electromagnetic pollution in your home, this app will help you to localize the places where you can rest more safely.

WiFi Heatmap features also a set of tools that provide useful information about wireless signal around you and makes this app a powerful Wi-Fi analyzer. The app can work as a channel analyzer for nearby access point, helping you to optimize your own network (by decreasing interferences and increasing speed and stability).

Scanning performance can be significantly increased by using an external SS11 sensor. High speed scans in single channel mode, probe requests detection and no scan throttling issues are some of the features provided by SS11. For more details about SS11 please see http://optivelox.50webs.com/DL_en/ss0x.htm.

Note: this is the trial version of WiFi Heatmap Pro (https://play.google.com/store/apps/details?id=com.optivelox.wifiheatmap2), some functions might be limited.
