CatchUp
An app for catching up on things
... intelligent deeplinking into dedicated apps that will allow you to do so.
CatchUp features several services but is not an all-purpose client for each of these services, nor does it support login for any service, or the customization/filtering of their feed. It will simply display the front page of a number of different services in a per-service-themed, consistent, at-a-glance UI.
