Real Referee Card is a simple and effective tool designed for referees, coaches, and game organizers.

With a single tap anywhere on the screen, you can switch between fullscreen yellow, red, and blue cards — helping you give clear visual signals during gameplay. There's also a dedicated black screen mode where no card is shown, allowing you to play a whistle sound without displaying any color.

A whistle icon lets you instantly play a loud, sharp whistle sound — perfect for grabbing attention during a match or signaling timeouts.

No more physical cards or whistles — this app brings it all into your phone.

Features:
• Tap anywhere to switch between yellow, red, blue, and black screen modes
• Whistle icon available for quick sound playback
• In black screen mode, only the whistle is shown — ideal for neutral signals
• Fullscreen, high-contrast display visible even in daylight
• Clean design with zero distractions

Whether you're officiating a match, managing a training session, or supervising informal games, Real Referee Card helps you stay in control at all times.
