I don't think this will be a daily feature, but i thinks it's a good idea to post those nice Android applications i downloaded and use on my phone. Today i played with the network and i stumbled on a great WiFi tool that helps you to analyze your network. You walk around in the house, discover the black spots and get reccomandation to switch channels.
It' gave me a great insight of the networks in our street. Most Access Points are located in front of the house. I switched channels and reception indeed improved as promised.

The second tool i downloaded and enjoyed is network discovery. I does exactly what it says, discover machines and additionally you can do a portscan on the hosts. It can do reverse DNS lookups and lots of other informational queries.
