sjReplay makes video feedback during ski-jump dry training quick and simple. Place your iPhone at the side of the training area, choose the appropriate camera lens and tap Start. The app watches for a ski-jump crouch position and begins recording automatically. When take-off is detected, sjReplay creates a slow-motion replay covering the moments before and after take-off. The replay loops continuously, allowing athletes and coaches to review the complete movement without operating the phone after every attempt. When another starting position is detected, sjReplay automatically prepares the next replay.
