About this app

Oshiparty is a simultaneous viewing app that lets you watch videos from subscription apps and streamers' YouTube broadcasts at the same time, giving you the feeling of "watching together" with your favorite streamers, anime, movies, and sports.

Previously, simultaneous viewing required opening multiple windows on a PC or using two devices (smartphone + tablet), which was cumbersome. With Oshiparty, it's all done on a single smartphone.

What you can do with Oshiparty:

• Simultaneous playback of videos from subscription apps and VTuber live streams (YouTube)

• Watch two YouTube videos simultaneously

• All-in-one with just an iPhone or iPad. Simultaneous viewing anytime, anywhere.

• Works not only with live streams, but also with archives and regular videos.

Supported service: DAZN.

The following services are currently being prepared: U-NEXT / d Anime Store / Amazon Prime Video / Netflix / Hulu / Disney+ / DMM TV / DAZN / Abema TV / Lemino
