ScoreCam has two optional camera overlays to help you frame your shots — both are found in Settings → Camera Options:

• Level — displays a horizon indicator on screen so you can tell when the camera is perfectly straight. The indicator turns green when the device is level.
• Grid — overlays a rule-of-thirds grid on the camera preview to help you compose the shot. The grid lines do not appear in the recorded video.

To enable either overlay, go to Settings (the gear icon, top right) → Camera Options and toggle on Level or Grid. They take effect immediately on the camera preview screen.
