Looks to be yes. It redirects to https://one.one.one.one/ref?referrer=a029b85e-cfc8-47f1-8e83... then https://one.one.one.one/

I tried it, and it appears to be freemium. The basic level is WARP, and then there’s WARP+ which costs $4.99/month.

The difference isn’t entirely clear though. It says that WARP+ will “route your internet requests to avoid Internet traffic jams.”

It is. Confirmed by generating a link on the app which gives credit and it's the same format.
