What are some of the messaging apps you frequently use?

The only messaging app I use today is Facebook Messenger. Most of my family members and closest friends are on Facebook Messenger, which makes it easy for me to interact with them. I can also create group chats for better communication with my family and friends, and sharing photos is simple too. Although I have Viber, I no longer use it.
