What is Nap-Zap? Nap-Zap is a stylish wristband with a built-in electric shock alarm clock, and health tracker functionality. Oversleeping can be incredibly disruptive to work and home life, but sometimes a regular alarm just isn’t enough to rouse a heavy sleeper. The Nap-Zap wristband sends a mild electric shock through the wrist when the alarm goes off, rousing even the heaviest sleepers on time. Nap-Zap helps ensure wearers won’t oversleep and miss an important appointment or be late to work, no matter how deep their sleep! Nap-Zap also features a number of built-in health sensors, including a pulse and blood pressure monitor, temperature reader, calorie counter, pedometer, and sleep tracker, so it’s easy to keep a close eye on sleeping patterns and health statistics.
