Drawing heat maps of wireless network coverage with a radio-frequency spectrum analyzer is very expensive. But some apps car draw heat maps using other type of measurements at lower costs. Here is the top 5 WiFi Heat Map Sofware, selected either because they are cheap but accurate, available on mobile devices or with high performances because of specific hardware support.

Here are the best heat map software available on the market:

Available on iPad, iPhone and Mac with Apple M1 chip or later, WiFi Map Explorer is the cheapest professional-grade tool in this category (2.99$ on the App Store market for unlimited full license, including installation on 6 devices). Moreover, this is the only one that runs on Apple mobile devices: very useful when you do not want to carry a computer to every location where you want to take measurements. It is not only a tool to build WiFi heat maps, it is also an app toolbox with a lot of network tools that are not otherly available from web servers on the Internet. Although you do not need an app to resolve a DNS name, request a Whois database or map an IP address to its geographic location, you absolutely need an app to estimate the local network latency or throughput, to discover connected devices on the local network, etc. This is why WiFi Map Explorer will be your preferred swiss army knife for network exploration and troubleshooting: a network app with amazing tools that can not be replaced by Internet services.
Features:
- Build a heatmap of your local wireless network,
- Discover all devices connected to the local network,
- Scan and discover every open TCP ports on local or remote devices,
- Measurement of latency with local and remote devices,
- Measurement of ingress and egress throughput with other local devices running this app,
- Measurement of ingress and egress throughput with any TCP CHARGEN/DISCARD server,
- Measurement of ingress and egress throughput with the Internet,
- Run a TCP/CHARGEN service on your device,
- Run a TCP/DISCARD service on your device
