Mac
LagSync helps you fix audio delay and video sync issues caused by Bluetooth headphones and wireless audio devices.
If you've ever noticed that voices don’t match lips on YouTube, Netflix, Twitch, or other streaming platforms, LagSync lets you correct that instantly in real time.
WHAT IT DOES
Bluetooth and wireless audio devices often introduce latency, causing audio to lag behind video playback. Most video players do not provide fine-grained sync controls.
LagSync solves this by allowing you to adjust audio or video timing directly while watching content.
KEY FEATURES
• Real-time audio/video sync adjustment
• Works with most HTML5 video players
• Supports major streaming platforms (YouTube, Netflix, Twitch, and more)
• Millisecond-level precision tuning
• Lightweight and fast performance
• No ads and no tracking
• Settings stored locally in your browser
HOW IT WORKS
Open a video in your browser
Launch LagSync from the menu bar or extension icon
Adjust delay until audio matches video perfectly
PRIVACY
LagSync does not collect personal data.
No tracking. No analytics. No ads.
All settings remain stored locally on your device.
WHY LAGSYNC
Wireless audio introduces unavoidable delay due to Bluetooth encoding and device processing. LagSync gives you control over that delay so your viewing experience stays perfectly in sync.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Netflix now works on Safari.
• Twitch delay now works on Safari and can be changed mid-stream without reloading the tab.
• Heads-up: Prime Video isn't supported on Safari — it uses Apple's protected video pipeline, which blocks the methods LagSync needs. Chrome, Edge, and Firefox still work for Prime.
