Facebook Messenger Gets Good Reviews

Facebook Messenger is reported to be better than the full Facebook app because it focuses on messaging. The app gives feedback regarding whether messages have been seen.

The app has the ability to send SMS texts in addition to instant messages, and includes multiple settings for push notifications.

The app retrieves phone numbers from Facebook connections, rather than the iPhone contacts list -- reducing the chance that user will use an outdated or incorrect phone number.

Some duplication of messages has been reported.
