## What is FixMySync?

FixMySync measures the offset between your audio and video using the industry-standard 2-pop (slate clap) method — giving you a precise millisecond reading you can dial in directly on your camera or audio recorder.

HOW IT WORKS
Record the countdown screen with your camera while FixMySync plays a sync tone. The app detects the visual 2-pop frame and the audio spike, then calculates the exact offset between them.

FEATURES
• Precise millisecond sync measurement
• Works with any camera or audio recorder
• Supports 24, 25, 60, and 120fps
• Review and compare past calibrations
