Covert is an app that makes it possible for you to browse the web privately via Safari, without adding any icons on your dock or springboard. To activate, simply open Safari, click the button to navigate pages, and then select private browsing. 

When you do this, Safari will no longer use cookies or keep search history. To de-activate, simply follow the same process in reverse; your cookies and search history will be replaced as they were before you started browsing.

This application is great for those of you that might share a phone, or wish to keep your browsing history secret from people that might use your phone when you're away. It's also great for preventing websites from storing your private data.

Of course, you won't be able to use any websites that require a secure login, but that's a fault of the way browsers work, not of the app.

The app isn't sexy, and it doesn't have any advanced features that I can see, but it does what it's supposed to, easily and for free. 

Being that this is the first of it's kind that I've downloaded and installed, I have no other app to compare it to, but overall I'm happy with this one. 

Some feature improvements I'd like to see are the ability to clear cookies and search history completely, the ability to set exceptions, and the ability to cloak the option in my browser. Overall though, it's a good free app.
