Google Now adds cards from 70 third party apps
New Google Now cards from ABC News, feedly or Circa keep you up to date and informed on the latest news, and cards from Eat24 tell you when your food delivery will be arriving. A daily card from Allrecipes gives you a daily recipe to whip up, and cards from Runkeeper, Jawbone, and Adidas will motivate you to meet your fitness goals. When you're eating dinner out, you can pay for the meal using OpenTable's Google Now card.
Adding the new cards to Google Now means you need to watch out for the latest update to the feature, which has already started to rollout in the Google App Store. If you have the app installed, go to the Play Store and check "My apps" to see if you have the updated version waiting for you. Even if you have the latest build of Google Now, it still might be a few weeks before the new cards start to appear on your device.
