Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

What's New: • Two new ways to step through frames, switchable from the buttons next to the time display • Jog wheel: turn the dial in the corner to move one frame at a time, with fine control and nothing covering the video • Ruler: drag the scale at the bottom to scrub frame by frame; it stops exactly where your finger stops • Built from your feedback about tapping fatigue and fingers blocking the video
