And I should add that I think using a ‘Based on Solid’ app should feel no different to any existing app. The complexities, benefits etc will be hidden to the user.
However if they go to their POD provider they should be able to see their PODs, manage the sharing of that data and link to the apps to see what data (photos, chats etc) that app is creating.
Does this make sense as a concept…
You have a one stop view of all your PODs and who is requesting access
Clicking on a POD shows you who is sharing that data and the controls to add or remove access. It would also have links to the application etc
