Tilt your phone and watch the sand shift. Flip it over to start the timer. Feel time through flowing sand, not digits. Tilt your phone and watch the sand flow with gravity. Flip it over to start the timer. Sunadokei is a timer app that lets you feel time. Instead of a digital countdown, you see sand grains falling one by one, giving you an intuitive sense of how much time remains. Powered by SpriteKit physics and CoreMotion tilt detection, it delivers the tactile feel of a real hourglass. Realistic Sand Physics Tilt your phone and sand flows with gravity. Shake sideways and it ripples. One-Tap Quick Start 1, 3, 5, 10, 25, or 60-minute presets. Custom durations also available. Time-of-Day Backgrounds Morning orange, midday sky blue, evening sunset, nighttime indigo. Seasonal Sand Colors Cherry blossom in spring, aqua in summer, amber in autumn, silver in winter.
