I think it is going to be a very useful app as it allows using apps on top of Ethereum network (as a browser) and messaging. Since there are and will be tons of apps built on top of Ethereum, I think this kind of browser will have many users in the days to come.

The only thing is we need some of its tokens to use "simple" services like push notifications. That may dissuade many users from using this app.

Since I could not find rival apps, I think this has good potential!
