Fireworks 4K turns your Apple TV into a fireworks display. The app plays high-quality 4K videos of real fireworks against the night sky. You can use it during parties as ambient wallpaper when you want something nice on the screen. The app includes a countdown timer. Set any date and time, and the countdown will show on screen. When it hits zero, fireworks start playing. This works well for New Year's Eve when everyone watches the clock before midnight. Also useful for Christmas Eve gatherings, Diwali celebration nights, Fourth of July parties, birthdays, or any event where you want a visual countdown. HOW IT WORKS Open the app, and fireworks start playing immediately. Use your Siri Remote to swipe left or right between different videos. Each one shows different fireworks with various colors and patterns. Press the center button or Menu to open settings, where you can set up the countdown timer or pick a specific video. COUNTDOWN TIMER The timer has preset options for quick setup. Pick a duration and press Start. For specific dates like New Year's Eve or a birthday at midnight, use the custom date picker. Select year, month, day, hour, and minute. The countdown displays cleanly over a dark background, so it looks good on your TV during a party. When the countdown finishes, the app automatically switches to fireworks playback. No need to grab the remote at midnight. VIDEO COLLECTION The app comes with multiple 4K fireworks videos. All loops seamlessly, so you can leave it running for hours without interruption. Browse videos in settings where each one shows a preview thumbnail. Turn on shuffle mode if you want random variety instead of watching the same one. Many people use this as an ambient display. Instead of turning off your TV or staring at a blank screen, put on some fireworks. It adds atmosphere to dinner parties, holiday gatherings, or regular evenings at home. The night sky background keeps the room from getting too bright. REMOTE CONTROLS Everything works with the Siri Remote. Swipe left or right to change videos during playback.
