Help me understand

Let me know if I'm getting these points right.

1. The Appics app is simply interacting with the Steem blockchain.
2. Appics is creating a token (APX) on the Steem-engine that runs on the Steem blockchain. Each time a person gets an upvote, they will get both Steem and APX?
3. If they want to convert this to EOS they would use the "Appics Foundation Account" as the middle-man to convert from Steem to EOS? Similar to Blocktrades.us?
   

If so, is this foundation charging a fee to convert back and forth?

1. EOS has no part of the app. EOS only becomes a part of the conversation when wanting to convert from STEEM to EOS.

Would be great to get some clarity on these 4 points.
