When you receive an email asking you to "Check your account" for some strange reasons, probably it's a phishing mail.
Usually, phishing email take you to some web page,
similar to the regular login page of your bank ...but it's a trick!
This login page is somewhere and not in your bank server.
This app checks the real server and show you who is the tricker.
Simply open your mail and holding down the finger on
"Check your account" select copy.
Open NoPhishing and push Discover button, that's all.
Easy and useful!
