My DNS allows to change your mobile/wifi DNS without root by routing your traffic through a local VPN.
It also comes also with an handy network speed meter icon on status bar for devices with Android 6.0+

Why it's not free and how it differs from other DNS changers?

My DNS, like similar apps, needs to run in background the whole time so it's imperative to be efficient.
It's also imperative to be as transparent as possible since it runs a VPN service on your phone.
