Synkplay vs SyncPlay

Synkplay is an open-source third-party client for iOS that lets you watch anything in perfect sync with your friends no matter where they are. It is fully compatible with any client or server that implements the open-source SP protocol, meaning you can seamlessly connect with friends regardless of what platform they are on. Synkplay is developed and maintained by yuroyami

SyncPlay is a professional video synchronization app designed to play videos perfectly in sync across multiple iPads. Built specifically for stage productions, theater, live events, and exhibitions where precise timing is critical. Unlike standard streaming apps, SyncPlay does not stream video data. Instead, it relies on locally stored video files on each device, transmitting only precise timing signals (Play, Pause, Seek) over the local network. This ensures frame-accurate synchronization with absolutely zero streaming buffering. ■ Key Features Completely Offline: No internet connection required. Works seamlessly with any local Wi-Fi router. Auto-Correction (Heartbeat): If network interference causes a slight delay, the heartbeat mechanism automatically snaps the guest video back to the precise host timeline within seconds. Host & Guest System: Control everything from one "Host" iPad, while all "Guest" iPads follow instantly. Blackout (B.O.): One-tap blackout button for theatrical transitions. Audio Safety: Guest devices are forcibly muted to prevent audio echoing in professional sound environments. ■ Pricing Tiers [Free Version] Access to Room A only. Connect up to 2 Guests per Host (3 devices total). [SyncPlay Pro (One-time Purchase)] Unlock all Rooms (A, B, and C) to prevent interference across multiple adjacent stages. Connect up to 8 Guests per Host (9 devices total). *Note: Only the "Host" device needs to purchase the Pro version. Guest iPads can join Pro rooms using the free version. ■ Best Practices for Live Events For live performances, we highly recommend enabling "Do Not Disturb" and "Guided Access" in your iPad's iOS settings to prevent unexpected notifications or gestures.
