Project Overview

SyncTV App is a cross-platform client for synchronized watching rooms, written in Flutter and covering Web, Android, iOS, macOS, Windows and Linux. It brings shared playback, room management, media providers and real-time conversation into one app, working together with the self-hostable SyncTV server.

Distance stops mattering when you watch together.

Key Features

• Synchronized playback: shared play, pause, seek, speed, source and playlist navigation with live drift correction
• Complete room experience: discovery, guest access, membership, permissions, favorites, chat, danmaku, history and administration
• Broad media surface: on-demand video, livestreams, direct URLs, HLS, DASH, HTTP-FLV, RTMP, NAS products, private clouds and media servers
• Voice communication: room-scoped WebRTC voice with optional media P2P and transfer metrics
• Modern authentication: password, email, OAuth2, native passkeys, TOTP and server-directed multi-factor flows
• Multi-server isolation: credentials, preferences, caches and identities separated by normalized server address
• Native viewing: fullscreen playback, compact player and picture-in-picture, platform volume and brightness controls, responsive layouts
• Six platforms: one experience across Web, Android, iOS, macOS, Windows and Linux

Target Audience

• Couples and friends watching together remotely
• Households running self-hosted media services
• Community hosts organizing watch parties
• Operators needing room-scoped permission systems
• Heavy NAS and media server users

Quick Start

1. Deploy or locate a usable SyncTV server
2. Download the client for your platform and enter the server address
3. Sign in, then create or join a room
4. Pick a source and start watching in sync

Core Advantages

• Precise sync: drift correction keeps everyone nearly on the same frame
• Self-hosting friendly: the open server keeps data in your own hands
• Wide provider ecosystem: mainstream platforms, NAS, media servers and direct links in one place
• Watching and chatting unified: built-in danmaku, chat and room voice

Notes

• Availability of third-party platforms and livestreams depends on the source sites and network
