Does it only work on Brave Browser? Does it have a mobile version?

I do like the idea of having Brave setting up the "webchannels" into the polkadot ecosystem, wonder about how sustainable this is with the degree of change we are facing today in the network. The user base already knows about privacy and security and with that 1/2 the battle is won, Now do we have what it takes in the ecosystem to device a social interaction tool that uses the ecosystem datafeeds? so we can absorb the user base!
