## What is Greenizer?

Greenizer turns your iPhone or iPad into a clean, static tracking screen for photo and video workflows.

Use it as a colored replacement area or tracking reference when filming a device screen, product shot, prototype, or visual effect setup. The app displays a full-screen color field with high-contrast corner markers that can be tracked later in your preferred photo or video editing app.

Swipe left or right to change the screen color, pinch to adjust the marker size, tap to show or hide the status bar, and long-press to toggle maximum brightness. Your settings are saved automatically, so the screen is ready the next time you open the app.

Features:
- Full-screen static color display
- Multiple background colors
- Trackable corner markers
- Adjustable marker size
- Status bar toggle
- Maximum brightness toggle
- Works on iPhone and iPad

Please note: Greenizer does not edit photos or videos. It is designed only to display a static, trackable screen for use with third-party photo and video apps.
