Have you ever had one of those tough days when you are tired and can’t seem to stay awake at work? You certainly wouldn’t want to be caught sleeping at work. That’s where Spark comes into play. This watch makes sure you never fall sleep at work or during an important event. It has two motion sensors to track movement velocity and frequency. When it detects that you have fallen sleep, Spark will gently vibrate to wake you up. You can adjust the intensity of the vibration to suit your own preferences.
Spark looks good and can get you out of trouble when you are having a long day. It is on Kickstarter.
