Could you please tell us about the browser and app you are planning to create. Are the Mass coins part of it? or is it something similar to Adblock or Brave browser?
Sorry for later answer, I will tell some more details about what we are going to do.
First of all, we will extend http protocol so Mass users will tell important information about privacy rules to website. We expect, that other browsers like Brave or Cliqz will support our protocol extension. Then we will give some ways for websites to pay user or get payment, arrange paid ad show or something else.
Draft version of protocol extensions will be available in 1 week.
What about our products. We are going to be like Ubuntu in Debian World.

Our first product arranged for late December browser extension for blocking ads, user data settings and test micropayment system.
Any reason that we need to buy this? I mean any feature or function make your project unique? Like people buy eth ico for smart contract, maidsafe ico for decentralized network.
