I am not sure if SmartVPN pro is a full VPN (ignoring the name of the app). It has secure DNS and it encrypts HTTP traffic but thats about as far as it goes.
Also, I would have thought having just a VPN wont block trackers which is what the smartVPN Pro offers i guess.
AFAIK the basic option doesn't include Secure DNS and HTTP. So the premium adds them on the top.
In addition to their predefined black lists you add your own urls/api calls for blocking. I have been doing this to the point that some apps have stopped working. So, I have everything maxed out for blocking accd. to their presets and on top i add my own.
I am still on 7 day free trial, and i think i will pay for 25e / year subscription which i think is reasonable for me.
I don't think I will get this service, there is limited information on what it actually does, says it blocks 5000 trackers, that's just a start, nothing to write home about.
It's € 36 here per annum which isn't that bad if :
1: I didn't already use a VPN (NordVPN).
2: They provide much more information on what they actually do.
Not saying they are shady (at all), just think the website is a bare minimum, not up to the task of providing enough
information.
