Rumii is a social VR app intended for business and educational use. A January 2018 UploadVR profile on Rumii notes:
With over 500 companies signed up in Early Access after launching last year, rumii is a social VR app with a difference. Instead of meeting up with friends to share videos, hang out and play games, the app is designed as a professional tool for work meetings and education spaces. Aiming to replace video conferencing, users adopt virtual avatars and then communicate over voice chat while sharing materials over a range of features like desktop sharing, 3D model loading and web browsing.
Among its features, Rumii offers a 3D model loader, a whiteboard, screen sharing, and file sharing. Rumii offers free and paid plan pricing. It is available on Steam.
