Because it's not immediately clear, this is a project developed by Coinbase, but under its own brand. The demo, which is available on the Apple Store and Google Play store uses TestNet Ether for now.
Yeah, I found it confusing that the ownership of the project was nowhere mentioned on tokenbrowser.com. The code seems to be copyrighted by "Token Browser, Inc" so I'm curious what sort of entity that is, whether it's just owned by Coinbase or what.
