Luna is a social app for video chatting. It allows you to meet new people around the world, make friends, and talk with them. The video call function is the same as Skype, so you don’t need to worry about privacy leaking to others. It is also similar to Google Meet, so you can chat with a lot of people at the same time.

You can use text, pictures, and video calls to communicate with friends, and you can also send them gifts. The video call function has a translation function, so you can break through geographical restrictions to make friends and get to know more about the other person.
