Time management meets digital art. Pixel Timer is a unique hourglass app powered by realistic physics. Unlike standard countdowns, it visualizes the passage of time through thousands of falling pixel grains. Whether you are working, studying, cooking, or exercising, this app makes every second visually satisfying. IMMERSIVE PHYSICS The sand isn't just an animation—it's a simulation. Tilt your iPhone, and gravity shifts instantly. Watch the sand slide, tumble, and pile up just like in the real world. PERFECT SYNCHRONIZATION We have engineered a smart flow control system. No matter how much you tilt the device, the sand is calculated to run out exactly when your timer hits zero. It combines the fun of a toy with the precision of a tool. KEY FEATURES: ・Gravity Control: Interactive sand that reacts to your device’s movement using the gyroscope. ・Smart Valve Logic: Even if you turn your phone upside down, the sand flows correctly and never accidentally reverses. ・Focus Mode: Tap the screen to hide all buttons and digital numbers. Immerse yourself in the pure flow of sand. ・Flexible Settings: Set timers for seconds, minutes, or hours. Perfect for the Pomodoro technique or long study sessions. ・Color Customization: Choose from vibrant neon colors (Cyan, Magenta, Gold, and more) to match your mood. WHY PIXEL TIMER? Traditional timers can be stressful. Pixel Timer provides a calming, visual way to track time. It helps you stay in the "flow" state, making it an ideal companion for deep work or relaxation. Download Pixel Timer today and let gravity help you focus.
