Hourglass: 3D Sand Timer

Clear glass, flowing sand, and time for you. Set 1 second to 1 hour, follow your countdown on the Lock Screen, and enjoy a look that follows Light and Dark Mode.

Watch sand flow and make a little time for yourself.

Hourglass is a 3D hourglass that responds to your iPhone. Clear glass, golden sand, and a look that follows Light and Dark Mode bring a quiet moment to reading, studying, working, or taking a break.

• From 1 second to 1 hour Choose a duration with separate hour, minute, and second wheels. Start quickly with 30-second, 1-minute, 5-minute, 25-minute, and 1-hour presets.

• Adjust the time already flowing Tap the large remaining time to add or remove time. A running hourglass keeps running; a paused one stays paused. Changing the total duration at the top refills the glass for a fresh start.

• Lock Screen and Dynamic Island Follow the remaining time and status outside the app with Live Activities. Pause, resume, or end your timer from the Lock Screen or expanded Dynamic Island. Dynamic Island appears on supported iPhone models.

• Sand that follows your tilt Tilt your iPhone to change the sand surface and falling direction, and slow the flow. Hold it sideways or lay it flat to stop the flow.

• Flip it to let time flow again Collected sand becomes your new remaining time. After 4 minutes of a 10-minute hourglass, a flip leaves 4 minutes. Text and controls also rotate when you hold your iPhone upside down.

• Desk mode for a steady countdown Set your phone down and choose desk mode for normal flow at any angle. You can still flip with the on-screen button, or expand the hourglass for a closer look.

• Make it yours Korean and English follow your iPhone language automatically, with a manual choice in Settings. Choose the completion chime, haptics, screen-awake behavior, completion notifications, and Live Activities separately.

No account, ads, or in-app purchases. Core features work offline. Preferences and timer progress are stored on your device.

About time displays The number in the app represents the remaining sand at normal flow speed. In motion mode, Live Activities show the estimated time until completion at the current flow rate, which can be longer. Away from the app, time continues at the last direction and speed; new motion is not tracked. Choose desk mode for a steady countdown.

The Live Activity countdown stops at zero, but its card may remain because of iOS background behavior. Reopen the app or use End to clear it. Live Activities and completion notifications depend on their separate settings and iOS permissions.
