The concept is interesting but as a developer I do not completely understand the pain. However, this is just my opinion and other devs might need this. Having said that, I'd love the UI and the use of the wearable. I think finding new ways for devs to get things done is interesting. Also, integrating this as part of other editors is the way to go,

The product has great value to teams, especially at the code-review stage. Challenge is to find a model that can monetise effectively, whilst keeping it open to community scaling

Interesting concept, free model and subscription model would be good. Might want to think of getting recommendation or reference engine together for the community of developers. Will need to be community oriented...
