Echoes has finally made its way over to iOS from the Mac to turn your existing Macs and iOS devices into a home intercom network. With Echoes, you can send quick voice messages to other Mac and iOS users on your local network without having to setup the app or dial a connection.
Echoes for iOS allows you to:
Announce to other users running Echoes on your local network
Announce to everyone, groups of people you configure, or individuals
Quickly reply to the sender of the last received announcement
Replay last received announcement in case you missed it
Use the iOS app to make announcements when you are not at your Mac
