Kosmi Old Versions APK

Kosmi Inc.

Kosmi is an online watch-party and virtual hangout app for friends, couples, and groups who want to spend time together from different places. Users can enter shared rooms to watch videos in sync, play multiplayer games, browse content, or simply talk. Built-in text, voice, and video chat keep conversation alongside the activity instead of splitting it across several services. Room search, invitations, notifications, and separate chat access help people return to their groups, making Kosmi a flexible hub for movie nights, game sessions, and casual online meetups.
