Smartphone manufacturers and tech companies are racing to make their products the most user friendly so people will buy them. That's why they're sinking time and money into personal assistants like Apple's Siri, Microsoft's Cortana, Amazon's Alexa and Google's Google Now.
While they're all impressive, Google Now (Android, Apple, Windows Phone; Free) has had the edge in predicting what you need to know before you know you need to know it. For example, it might alert you to a traffic jam on your usual route to work before you walk out the door.
Google Now presents this information on "cards" you can tap and swipe through. So you'd have the traffic card, the contacts card, the weather card, etc. However, these cards were mostly confined to services Google itself could offer.
That's now changed and it's made Google Now even more useful that it was before.
