I would say "I'm happy to answer questions" but I'm not sure what I could answer; for a while now, I frankly forget that I have it even installed. It pretty much Just Works.
Warp is a set of apps that will set your phone (and with this, today, your computer) to use 1.1.1.1 for resolving your DNS. But additionally, it uses the Wireguard protocol to connect, which is a VPN protocol. This hides the contents of your connection from your ISP or network provider. It does mean you're connecting to Cloudflare, and so we've made a bunch of privacy commitments, and gotten external auditing to back those up: https://news.ycombinator.com/item?id=22747770
The above is all free. You can pay a small subscription fee to get access to Warp+, which uses Cloudflare's "Argo" product to route your requests faster.
Does that make more sense?
If I'm trading one centralized service for another, there is no net gain.
(if the address you are trying to go to is hosted by Cloudflare, they route it using your normal connection so that it'll be quicker than going an additional couple hops to the WARP server and then to the Cloudflare dc nearest to the WARP server. you could say that this kills the privacy argument, but using their VPN at all means they can see what sites you are going to, so you'd already be trusting that they don't log.)
And fwiw, since I'm sure someone will think it - I don't want to manage my own VPN on some remote server. Not only would I put myself at risk because I don't have the experience to manage a secure server of such importance, but all I did was move my risk from my ISP to some other endpoint (VPS hosting/etc).
It feels like a game of risks no matter what you do.
