Wps wpa wifi tester is good for break wifi password for urgent use. It shows all running wifi around area. In latest update the developers of this add 'wps only' option which is good. It shows a lock type option against all wifi's, if this is green then it is wps enabled and it try to connect it. If it is red then it does not connect it, because that wifi is with wpa2 security. These are the features of this. I also use this app. When I install it on my device, it shows list of wifi's around me. But when I try to connect it ask, your device is not rooted. It is very bad. But I need this application, so I rooted my mobile. Which is not good.
