The app indicates when messages have been sent, when they have been read, and when someone is typing.

Messages clearly indicates whether messages are being sent over iMessage (blue) or SMS (green) where messaging rates apply. iMessages do not count as SMS messages with your carrier, instead they use a negligible amount of data to send over Wi-Fi and cellular data networks.

Short voice recordings/messages can be quickly sent, and messages can be easily dictated into written messages as well.

For example, you can play games like pool or you can show someone a destination to go to.

UI is minimalistic, and clear. And there is a plethora of stuff on the left of text box if you wanna use them.

You can just message them using their existing phone number or Apple ID and they will get your message.
