Virtual Hour Glass app for iPhone and iPad
Virtual Hour Glass emulates a real hour glass. Watch the grains of sand turn as you turn your iPhone. Hour Glass has different time options ranging from 30 seconds to 5 minutes.
You can also turn On/Off to Emulate a real hourglass, giving you the ability to have a true timer not solely based on steady hands. Once the time is up it gives a simple buzz/vibrate to let you know the time has expired.
