Overview

Product summary

Review the store description, core capabilities, and common use cases.

ReactSync keeps a reaction video and its source video perfectly in sync across two browser tabs — automatically.

Pick your reaction tab (Tab A) and your source tab (Tab B), enter the time offset between them, and hit Sync. From that point on, pressing play, pause, or seeking in either tab instantly mirrors the action in the other. No more manually pausing two videos every time you need a break.

FEATURES

• Automatic sync — play, pause, and seek events mirror across both tabs in real time

• Time offset — set how many seconds Tab A leads Tab B (supports positive and negative values)

• Nudge controls — fine-tune the offset in 0.5s, 1s, or 5s steps while watching
