Matt Galligan:
The trouble with the pop up approach is that the app was inevitably interrupting the user’s experience. A method that’s more integral into the experience is the next step — we call this the integrated rating.
For Circa we decided to place an integrated rating in the middle of our list of news stories. That way, someone could scroll right past it without having to interact with it, as opposed to a pop up which requires interaction.
