I can see problems arising since Uninkd essentially owns the app but is licensing use of the publishing platform. This leaves the author out of the various sales details and metadata that iTunes Connect offers.
edit: I would also update your revenue calculator to factor in the various fees.
All your issues articles, are available online via uninkd as well. So when people share an article on Facebook or Twitter, they'll share a link to the online article.
When it comes to analytics, we haven't implemented anything yet. It is something we want to do in the near future though and for now, we could give you access to and App Annie account where you can see all the analytics on the app you could wish for.
We are still developing the product and we have been thinking about making it optional.

The reason we are not implementing a signup when reading articles, is that it would make it impossible for your magazine to be shared. People want to share what they read and they often have friends who are interested in the same things. Those friends are all potential subscribers and it would be a big barrier for them if they had to subscribe in the app before they could read a single article.
If the subscription also allowed a user to view the articles online, I'd be fine with that.
We think it's too much of a barrier if people have to sign in to read a single article.
There won't be a single place where people can find all of your articles though. They will only be visible through people who share them.
Enabling people to easily share and let their friends read a single article gives your magazine a chance to spread.
