Facebook has released a major redesign of its Messenger iPhone app in the App Store. The update is a significant departure from the previous version, and Facebook has designed it with iOS 7 in mind. Profile pictures are circular like they are for contacts in iOS 7, and Facebook is using a brighter color scheme that comes close to mimicking the look of Apple’s Messages app.
Badges now appear over friends’ pictures when they are on Messenger. Facebook has done a good job of stripping pretty much all of its normal branding out of the redesign, so Messenger looks like a typical chat app now.
A key addition is Messenger’s new integration with phone numbers. If someone has their phone number listed on Facebook or in your iPhone’s contacts, you can enter their number in the app to find them on Messenger. You can also message people through the app by using phone numbers in your contacts list.
