"This app allows you to easily alter your hosts file to add websites which you don’t want your computer to be able to access, which is good for protecting your family against harmful websites, and also can stop you accessing websites that drain your time, such as Facebook and Twitter. You can alter the hosts file yourself but it isn’t particularly straightforward and requires using the Terminal application. With this app you only need to enter 1 command into the terminal (which the app prompts you to type in as it opens Terminal for you). Once that is done the app is allowed to continue to alter the hosts file. I think it is a really good app and easily accomplishes an otherwise complex little tast. Thanks to the makers of it. (^-^)"

"Was using a host file addon but wasn't reliable. This program is what a host editor should be. Simple and effective! Great stuff."

"Does exactly what it's supposed to do and does it with minimal fuss. Sometimes the UI is mildly counterintuitive, but it fills its niche and just works."
