Android: Earlier this year, Google started allowing third-party app developers to place cards in Google Now. Today, the company has announced that it's greatly expanding this program with support for 70 new apps, including Spotify, Feedly and Runkeeper.
This expansion will allow dozens more apps to add cards to your Google Now feed, which can get a little barren if you're not on holidays or obsessed with stock quotes. The cards will act as extensions of the apps you already have installed on your phone. You can browse the full list of possible cards here.
