There is another new VPN released recently coming directly from Tor project, and it is called Tor VPN.
This sounds a lot like Orbot, and the only difference I can find is that Orbot mobile doesn't seem to be created by the Tor Project
itself (unlike Orbot, which is created by
themthe Tor Project).
it is strange to me they are offering this VPN totally for free.
I wouldn't call it a VPN, it's just an app that uses the existing Tor network, which runs on nodes paid for by volunteers (and intelligence agencies, and data tracking companies
....).
