I love how easy it is to use this app! It's so simple to set up groups with your contacts and you can even add people who aren't already part of a group by using their email address or phone number. You have complete control over what information gets shared, and there are no ads. This makes communicating privately much more convenient than other apps. The only thing I dislike about this app is that sometimes when I'm trying to send a message out into a larger group, it will not let me know if someone has received my message until after they've read all of them. That said, I still think it's one of the best ways to communicate quickly and easily with large groups without having to worry about being seen as too public. We're able to organize our team meetings through this app because we don't need to share any personal contact info beforehand. Also, since everyone uses their own device.
