Pi-hole

Please, don't download this app if you don't know what is the PiHole Project.

It runs on home-based tech, like the inexpensive and energy-efficient Raspberry Pi, to protect all of the devices on your home network from unwanted content.

A person you know has cared enough to make the Internet safer for you, and more enjoyable for you to use!

Blocklists, consisting of unwanted content, are curated by volunteers outside of the Pi-hole project, and are regularly updated remove legitimate websites that have been accidentally blocked. Fortunately, blocked sites you need right now can simply be unblocked by the administrator of the Pi-hole on your network; you just need to let them know.

You can manage your DNS server with this app.
