A simple review for a simple app. You must be rooted to make use of this app. This app does what it says on the tin, you install it, periodically update your host files (you will be notified when you need to update) and your Android will be relatively ad free. This doesn't seem to get rid of all ads, some are delivered in unavoidable ways, but it does a good job. Plus, it's free so you can't really justfy complaining about it's apparent limitations.
