Missed that last message? Couldn't remember the details of a conversation?
Click on a friend or group to see the Message History.
Here you can replay whole conversations or single messages on a messages timeline with amazing accuracy.
You have total control over what you store and for how long. Messages are stored on your own device. Not on a server somewhere.
Sometimes you need to quickly message a whole group of friends.
With SayWe it's as easy as messaging a single friend. SayWe will handle delivering your message to each member of a Facebook group.
Replies are kept within the group's timeline. This is an awesome way to coordinate quickly.
