Visual Countdown Timer with Traffic Light: This timer features a 200-minute countdown with a traffic light display. The green light stays on for 90% of the task time, the yellow light blinks for the final 30 seconds (10% remaining), and the red light with sound signals time's up. Helps children understand time visually without needing to read numbers. Visual and Audible Alerts: One-touch start/stop button, LCD display, and dedicated settings for time, alerts, and reset. Adjustable volume with 4 alert options (gentle beep, chime, buzzer, melody). Suitable for classrooms, kitchens, quiet spaces, and activities like cooking, fitness, or time management. Safe Charging & Long-Lasting Use: USB-C rechargeable with 36-hour runtime on a single charge (4.5 hours charging time). No removable batteries, reducing choking hazards. Red charging indicator shows status. Ideal for both cordless portability and stationary use. Child Safety Mode & Memory Function: Child Lock disables buttons to prevent unintended adjustments (recommended for ages 3+). Automatically saves previous settings (countdown duration, alert tone) for quick reuse without reprogramming. Time Management Tool: Replaces abstract numbers with traffic light color blocks to help children establish time rules through the game mechanism: "Sprint on Green, slow down on Yellow, brake on Red." An ideal teaching aid for home and school. Whether you are a parent, teacher, professional, student, or child,
