An iphone/ipad app to display an hourglass timer with a digital readout below. The timer duration is set and the countdown starts. The "sand" in the hourglass starts to trickle down. When the countdown reaches zero, and the sand has all trickled thru the hourglass, an alarm sounds and the user must shake once (or twice) to stop the alarm. The shake does 2 things. It stops the alarm AND resets the timer to start the countdown again. The countdown will repeat the previously selected timer duration. A "Finish" button will close the app.
A more detailed design concept is attached.
