There’s the Wireguard client which you can use with Blokada.
I have a question about blokada. So I’ve had it on since I had the app installed and now it suddenly says deactivated does this mean I have to get blokada+ or what the hell
You can also just get the Cloud subscription which is much cheaper. You can find details here: Important announcement regarding Blokada for iOS
Blokada blocks 99% are of your ads so you can watch a movie without ads distracting you
