We already have Monero for "anonymous currency with ring signatures". Isn't this a little redundant? Or is there a significant difference between the two coins that I'm not seeing here.
The difference is in the App. There hasn't been much information given yet on what kind of protocol the app will use, but apparently it will be more than just a mobile wallet for an anonymous currency. This app is meant to enable ordinary people to use Spectre on a daily basis for their payments, while retaining their privacy and not requiring much of a banking infrastructure.
The whole project is about Spectre.
Cash, which is what the currency for mobile use will be called. The network, which is similar to SDC, just acts as a backbone network.
The ICO was meant as a crowdfunding for this app, for the case you're still wondering. It raised a very low amount, like 13 BTC I think.
