Apple first started letting users experience Quick Reply on iOS 8 but only on their own Messages app. The feature allowed you to pull down on a notification and reply immediately without opening the app itself. Now since iOS 9 has come into play, Apple enabled other apps to access this feature – Skype and Facebook Messenger were given the go-ahead much earlier.
Today, WhatsApp finally joins them. Users who use watchOS 2.0.1 will also allow users to pre-set replies to answer WhatsApp messages, or just reply on your Apple Watch.
Available to update since early last week, iOS 9.1 added a slew of features, including 150 new emojis, and a smarter live photo. The latter added a rather intelligent ability to sense whenever you move your phone through its gyroscope; so if you were taking a photo of an object, the sensors of the gyroscope will track if you tilt your phone and cut off the photos after you moved your device.
Head on over here for a more detailed look at what iOS 9.1 brings to the table.
