10 Free and Low-Cost Mobile Wireless Tools, March 06, 2013 There's no replacing meaty, licensed tools for wireless network support. But a growing number of free and low-cost apps are available when all you have is a smartphone or tablet at hand. Most of the gems live in the Android space, so you iOS developers need to get to work.
Fing for iOS and Android
Fing is not a dedicated wireless tool. At the same time, a wireless network is part of a bigger topology and many of us are just as concerned with overall network operations as we are with deciphering Wi-Fi signal information. Fing is free for Apple and Android, and is a slick tool for figuring out exactly what a local network is made of from the host perspective. Utilities include network discovery, ping/traceroute, DNS lookup, port scanning, and more. It's crazy useful at a price that can't be beat.
