Very good!
Here are some Tools I use:
MAC Address Spoofer (Not on Play Store anymore, I have it on my Dropbox)
Fing - Node Scanner And Service identifier.
DroidSheep.
WiFi Kill (Same as the Spoofer, (Not available - It's On my dropbox)
dSploit.
aNTI PenTesting Suite.
Router Keygen (Available on Google Code - Bruteforces/Generates Keys based on vulnerable APs in which the algo has been broken.)
DNS Spoofer - 600MB Install - Again, not avail. on Play Store, - On My Dropbox.
And I use some others, I can't remember.

Most of the tools I use though, as spin offs of WiFi dictionary lists which calculates old algorithms.
Most of them use the same dictionary though.
