Why?

Why isnt there an ipad version on this app? Why are the insight numbers different between this app and the pages app? Why doesnt this app show the same information for each person who is admin on the account?

So much seems wrong with this app. Im not even sure I understand what the purpose of this app is... could someone explain why we would use this particular app, rather than FB or Pages?
