Anyway to use this in android?

I already use Firefox + ublock origin and it is enough for my browsing.

However I am looking for something to block ads also on apps.

Take a look at https://blokada.org/

It blocks ads in news and other apps for me.

Has it been working fine for you? It quite often stops working for me and I have to restart the service.

DNS66[1] has been working great for me but for some reason it misses a few ads unlike Blokada which never missed a single ad for me.
