KEY FEATURES
• Displays a frame counter and elapsed time
• Supports portrait and landscape orientations
• Uses a simple black background with white numbers

HOW TO USE
1. Position your iPhone where both cameras can record its screen.
2. Start the display and record the screen with both cameras.
3. Open the recorded footage in your preferred video editing software.
4. Compare the displayed frame counter and elapsed time in both recordings to examine their relative timing.
IMPORTANT INFORMATION
The displayed frame counter and elapsed time are generated by the app. They do not represent either camera's actual recorded frame numbers or exposure timestamps.
This app does not control camera recording, automatically synchronize cameras, import footage, or automatically calculate recording-time differences.
The app does not display full-screen high-speed black-and-white flashing patterns or Gray-code bars, and it does not force screen brightness to maximum.
The displayed numbers may still change rapidly. Avoid using the display if you are sensitive to rapidly changing visual stimuli.
