It's a very simple, yet realistic hourglass. - Choose from a 1-minute, 3-minute, or 6-minute timer (check the remaining time at the bottom of the screen to determine the correct time). - Swipe the screen horizontally or turn your iPhone sideways and then back to portrait to flip the hourglass over. - You can display the remaining time and play a chime when the timer finishes. - You can set it to rotate automatically once all the sand has fallen. Staring at it is soothing...maybe.
