ADSkip 

ADSkip is a powerful app that can effectively block all types of ads on the web pages that you visit. It will also handle the bandwidth-consuming video ads, removing them before they get to be loaded and played, as well as banners and popups.

ADSkip will do its job regardless of the network type that you're using, may it be cable, Wi-Fi, 3G or 4G networks. Furthermore, it works with any kind of browser and app.

ADSkip is also very reliable thanks to the fact that it uses a constantly-updated blacklist of websites that host the ads. You can also add URLs of advertisements that need to be blocked to this list, as well as allow ads on specific websites. In other words, this tool supports both blacklists and whitelists. Filtering rules are also available.

This handy ad blocker is also very easy to use and to configure. Its interface is neat, simple, and straightforward, allowing even complete beginners to use it without any problem.

In conclusion, since it's also completely free, I consider ADSkip a great choice for anyone in need of a powerful, reliable, and yet lightweight and simple-to-use ad blocking tool.
