At first the web was like a world where everyone could read books but only a few could write them.

Then later everyone could read and write but only a very few kept the books where they could do that.

Now with Solid everyone can read and write in their own books and share them with who they choose.

So a Solid app is one that uses read and write permissions on pods.

I would also add that a Solid app must work with Linked Data (to encourage interoperability, reusability with other services, etc). I can see the point of not adding that point, but the app wouldn’t be as valuable for the Solid eco-system IMO.
