FixMySync

Measure audio/video sync in seconds. Perfect for filmmakers, editors, and content creators.

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 • One-time purchase — no subscriptions
