Excellent stuff team!
I’m quite excited to see this materialize and cannot wait to use it as well as hear feedback from how customers and users interact with it - it’s all that ultimately matters. I’m very happy you decided to work on this and glad my tiny weekend demos inspire more and more people to develop things. I hope these sort of products attract more people to be exposed to Polkadot by either knowing that these things are possible on Polkadot or by integrating other ecosystems in a successful product that has Polkadot at its center or as the default option. Keep building and creating tangible things no matter the headwinds.
And by the way, mobile blinks is ~ solved, the trick for that is to develop an application that leverages iOS accessibility features to inject frames into running apps, check this out. 
I do think though that even if it remains a small trick for the mobile part (and perhaps a dangerous one if you read into it a bit more), it can still make for a great demonstrator especially for a more skeptical audience.
However for the mobile part, I would see a collaboration with our beloved ecosystem mobile wallets to be the pragmatic path ahead instead of setting course on creating your own mobile app, at least to explore making a simple proof of concept. I would have showcased a demo but I cannot get my XCode project to compile 
Good luck!
