This is just a trusted RPC connection right? You're not embedding any sort of light (or otherwise) client? Are you running the nodes on the backend, as opposed to outsourcing to someone like infura? What are you running if so (geth, parity, something else) and how (single node or multiple nodes load-balanced)? Curious to hear the setup.

The app uses Infura, just like MetaMask, but future version will allow you to specify your own RPC. Geth/Parity light clients are not quite usable on mobile yet, but they are improving rapidly, so hopefully in the future.
