I'm actually running Blokada, but both perform the same function.

Blokada does track how many ads it blocks and gives you a count (and notifications if you wish to be so notified [configurable]).

Both are free (as in the GNU 'freedom' definition as well as the 'beer' definition) so you could try both and see which you prefer.

I've used DNS66, but I think I will give Blokada a shot. I really wish either one would offer the option of using DNSCrypt!
