砂時計 - 物理演算 app for iPhone and iPad

This is an approximately 3-minute hourglass that uses physics simulation to recreate realistic movements.

You can enjoy watching the grains of sand smoothly fall under natural gravity while keeping track of time.

With a simple and intuitive design, its an ideal tool for meditation or improving focus.

When the gyroscope sensor is enabled, the movement of the sand adjusts in real-time according to the tilt of your device.

Each session offers a different atmosphere, allowing you to relax and experience the comforting analog feel within a digital space.
