WiFi Explorer Pro is a network analyzer made of 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 Explorer Pro 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.
